    [0001] The present invention relates to the field of dyeing of keratinous fibers and more particularly to the field of hair dyeing.
    [0002] The present invention relates to a process for the oxidation dyeing of keratinous fibers, in particular human keratinous fibers such as the hair, consisting in using on said fibers i) a substrate comprising at its surface one or more oxidation dyes. and ii) an aqueous composition comprising one or more oxidizing agents. The present invention also relates to a process for preparing the substrate as described previously, implemented from a printing method. The invention also relates to a sheet element pretreated with a composition comprising one or more oxidation dyes. It is known to dye keratinous fibers, in particular human keratinous fibers such as the hair to obtain so-called permanent dyes with dyeing compositions containing oxidation dye precursors, generally called oxidation bases such as orthoacids. or para-phenylenediamines, ortho- or para-aminophenols or heterocyclic compounds such as pyrazoles, pyrazolinones or pyrazolopyridines. These oxidation bases are colorless or weakly colored compounds which, when combined with oxidizing products, can give rise to colored compounds by a process of oxidative condensation. It is also known that the shades obtained with these oxidation bases can be varied by combining them with couplers or color modifiers, the latter being chosen in particular from aromatic meta-diamines, meta-aminophenols, meta-aminophenols and meta-aminophenols. diphenols and certain heterocyclic compounds such as indole or pyridine compounds. The variety of molecules involved in oxidation bases and couplers, allows to obtain a rich palette of colors. Conventional oxidation dyeing processes generally consist in applying to the keratin fibers a dyeing composition comprising oxidation bases or a mixture of oxidation bases and couplers with hydrogen peroxide (H 2 O 2 or hydrogen peroxide) with as an oxidizing agent, to let diffuse and then rinse said fibers. The resulting colorations are generally permanent, strong, and resistant to external agents, including light, weather, washing, perspiration and rubbing. However, it has been found that it is often difficult or impossible to obtain colorations having original visual results with the so-called conventional oxidation dyeing techniques. In particular, these methods do not make it possible to obtain, in a satisfactory manner, colored patterns, which can lead to original optical effects on the whole of the hair, which are both sharp and precise. These conventional oxidation dyeing methods also have the disadvantage of staining the hands of the user or the hairdresser during the application to the hair of the ready-to-use composition resulting from the mixing of the dye composition and the oxidizing composition. In the same way, this type of process can also cause unwanted spots on the scalp, facial contour and / or clothing of the user that may be due to application errors and / or run-off problems. compositions. These conventional oxidation dyeing processes also carry the risk of not leading to the final coloration desired by the user because of an error occurring during the handling of the dyeing and oxidizing compositions or in the wrong choice of the dyeing compositions. departure. It has also been found that the storage of the dyeing compositions and oxidizing compositions used to obtain the desired coloration may cause congestion and / or storage problems over time, particularly in hairdressing salons. These oxidation dyeing processes may thus not prove to be practical for producing many different colors depending on the different users.
    [0003] Furthermore, it is already known from FR2984087 to implement a staining or bleaching process comprising contacting the keratinous fibers with a substrate bearing a coloring or bleaching composition having a formulation that varies according to the position on said substrate in order to obtain a gradient coloration or discoloration. However, this document does not describe a process capable of producing precise patterns and / or of producing solid colorations. There is therefore a real need to implement a process for the oxidation dyeing of keratinous fibers, in particular human keratinous fibers such as the hair, which does not have the disadvantages mentioned above, that is to say which is in particular capable of leading on said fibers to stainable colors and / or to present original visual results, in particular precise color patterns, to reduce the problems of size and / or conservation of the compositions used, to minimize the risks of contact that may occur between the compositions used and the hands, the scalp and / or the clothing of the user and the risk of not obtaining the desired color. This object is achieved by the present invention which has for object a process for the oxidation dyeing of keratinous fibers, in particular human keratinous fibers such as the hair, which consists in using on said fibers i) a substrate comprising at the level of its surface one or more oxidation dyes, and ii) an aqueous composition comprising one or more chemical oxidizing agents. The method for dyeing keratinous fibers thus uses a substrate on which one or more oxidation dyes have been deposited. In other words, the substrate has been pretreated at its surface by a coloring composition containing one or more oxidation dyes. Thus, during the contacting of the keratinous fibers with the pretreated substrate and the aqueous oxidizing composition, the oxidation dyes present on the surface of the substrate dissolve and react with the oxidant, this in contact with said fibers to color them. which leads to colorings that can be united and / or colored patterns.
    [0004] In particular, the oxidation dye or dyes are deposited on the surface of the substrate and may be located at certain locations on said surface so as to represent one or more geometrical shapes in order to then produce one or more colored patterns on the keratinous fibers after contact between said fibers, the pretreated substrate and the oxidizing aqueous composition. In other words, the substrate may be pretreated in places with a coloring composition containing one or more oxidation dyes so as to make one or more colored patterns on the fibers.
    [0005] The dyeing process according to the invention thus makes it possible to produce, with great precision, colored patterns, which are visually clear, on the keratinous fibers. In particular, this method makes it possible to produce millimeter-sized colored patterns having all types of shapes, such as dots or waves, which are easily reproducible. These patterns can thus lead to original optical effects when they are then repeated throughout the hair. In other words, the dyeing method according to the invention makes it possible to obtain patterns, in particular of millimeter size, homogeneously throughout the hair, or in a localized manner on a part of the hair. These patterns may be whimsical from an aesthetic point of view or serve to mask an irregularity in the color or appearance of keratin fibers, especially in the case of regrowth or sharpening tips. Furthermore, thanks to the use of substrates comprising one or more oxidation dyes, that is to say substrates previously treated with a composition containing such dyes, this process makes it possible to reduce the risk of stains on the hands. , the scalp, the face and / or the clothing of the user. Indeed, this method makes it possible to avoid the problems of sagging and / or the errors of application of the dyeing and oxidizing compositions. In the same way, thanks to the application of such previously treated substrates, this process makes it possible to reduce the storage problem of dyeing compositions and oxidizing compositions used in conventional processes, which makes it possible to significantly reduce the problems of dyeing. congestion. In particular, the user may have at his disposal a larger number of substrates previously treated with oxidation dyes while generating a saving of space in hairdressing salons. Furthermore, the process according to the invention has the advantage of using previously treated substrates which are stored satisfactorily over a period of time which can range, for example, from a few days to several months. The oxidation dyeing process according to the invention also has the advantage of minimizing the risks of errors that may occur during the handling of the dyeing and oxidizing compositions or in the choice of starting dyeing compositions in order to obtain the desired coloring. The oxidation dyeing process according to the invention also makes it possible to obtain colorations and / or patterns whose colorations are powerful, not very selective and resistant to external agents (such as shampoos, light, perspiration or bad weather). In particular, the dyeing method according to the invention leads to obtaining patterns whose coloring is powerful and resistant to shampoos. The present invention also relates to a method for preparing a substrate containing at its surface one or more oxidation dyes consisting of depositing by a printing method a dye composition containing one or more oxidation dyes on the surface of the dyeing surface. a substrate. In other words, the dye composition is printed on the surface of a substrate by virtue of the implementation of a printing process in order to obtain a pretreated substrate. The substrate obtained is thus surface-treated with said composition based on oxidation dyeings before being used in the oxidation dyeing process according to the invention. The printing method for depositing the composition on the surface of a substrate may be a screen printing method, a flexographic method, an offset process, or a printing method using an inkjet printer or a laser printer. . This preparation method can be implemented within the hairdressing salon thanks in particular to the presence of an inkjet printer before performing the oxidation dyeing process according to the invention.
    [0006] The production of these pretreated substrates within the hairdressing salon and / or at the user's premises has the advantage of minimizing storage problems, especially with regard to oxygen, because the user and / or the hairdressers will be able to use the substrates in the minutes or hours following their realization.
    [0007] Alternatively, this method can also be implemented outside the hair salon so that the user only has to use the substrates to color the hair. In this case, the pretreated substrate can be provided to the user to achieve a solid stain and / or patterns on the hair.
    [0008] The invention also relates to a sheet element pretreated at its surface by a composition comprising one or more oxidation dyes. In other words, another object of the present invention relates to a sheet member having at its surface one or more oxidation dyes. In particular, the sheet member comprises one or more oxidation dyes that have been printed at its surface. The sheet element according to the invention has the advantage of being easily applied to the locks of hair. In particular, such an element can be positioned with great precision where it is desired to make the color pattern or patterns on the locks of hair. The sheet element has the advantage of being easily stored in the user with respect to the use of dye compositions used in conventional oxidation dyeing processes which reduces the bulk significantly . In addition, the sheet element can be prepared directly in the hair salon or in advance. Other objects and features, aspects and advantages of the invention will emerge even more clearly on reading the description and examples which follow. As indicated above, the oxidation dyeing process uses on said fibers a substrate which has been previously treated at its surface with a composition containing one or more oxidation dyes. The substrate may be in the form of a sheet element or another embodiment.
    [0009] According to a preferred embodiment, the substrate is a sheet element. The sheet element may be made of plastic, in particular thermoplastic, paper, metal, especially aluminum, woven, non-woven non-absorbent fibers, especially cellulose or one of its derivatives, or polyamide 6 6. Preferably, the sheet element is a sheet of plastic material, especially thermoplastic, or nonwoven material of non-absorbent fibers, in particular a nonwoven based on cellulose or a derivative thereof. In particular, the sheet element used in the coloring process is a plastic sheet. The sheet element may consist of a water-soluble material, which allows, for example, to be removed by washing the hair. The sheet member preferably comprises an assembly of a layer of a water-soluble material and a layer of a water-insoluble material, for example an aluminum foil.
    [0010] The substrate can be arranged to be closed around a lock of hair. In this case, such a substrate is for example provided with a fixing means for maintaining it in such a state, for example an adhesive disposed near an edge or a mechanical attachment relief.
    [0011] Preferably, the sheet element has a basis weight ranging from 20 to 300 g / m 2, more preferably from 30 to 200 g / m 2. The sheet element has in particular a thickness ranging from 40 to 1000 micrometers, preferably a thickness ranging from 40 to 400 micrometers, better still from 60 to 200 micrometers. The sheet element can be opaque or transparent. Preferably, the sheet element is transparent which facilitates its positioning on the hair, especially when one wants to make one or more patterns at a specific location of the lock or hair. In other words, the transparency of the sheet element facilitates the implementation of the coloring process, especially in the production of colored patterns, and improves its accuracy. The sheet element used in the coloring process according to the invention is preferably flexible and resistant. Preferably, the resistance of the sheet is greater than 300 kPa (TAPPIT403 standard). Preferably, the sheet member is water resistant. In particular, the water absorption of said element is measured by the COBB test 60 which corresponds to the ability of said element to absorb water during a contact of 60 seconds (whose procedure is given by the ISO 535 standard, measure TAPPI-T411). Thus the sheet element absorbs less than 100 g / m2, and preferably less than 40 g / m2 of water.
    [0012] Preferably, the sheet member is resistant to oily compounds. Thus, it is possible to use a so-called "food" paper, that is to say a complex of paper and polyethylene-type polymeric compound or paper and paraffin, capable of being a barrier to water and oils.
    [0013] The sheet element may optionally be covered with a deposit of an adhesive composition. This adhesive layer makes it possible to improve the adhesion of the oxidation dye (s) at the surface of the sheet element. According to a preferred embodiment, the sheet element, after treatment with the composition containing one or more oxidation dyes, may be covered by a protective means whose function is to protect the surface of said element of the outer elements. Thus the sheet element comprises one or more oxidation dyes that can be coated with a protective layer.
    [0014] Such a protective layer makes it possible to minimize the alteration of the oxidation dye (s) associated with humidity, light or oxygen in the air. Thus, the sheet element can be protected by implementing processes used in paper varnishing techniques (fatty varnish, acrylic, etc.), and in particular by using an aqueous or organic acrylic varnish composition. In this way, the sheet element containing one or more oxidation dyes may be surface-protected with a layer of acrylic lacquer.
    [0015] According to this embodiment, the sheet element contains one or more oxidation dyes and is covered by a layer of acrylic lacquer. In other words, the sheet element contains a layer containing one or more oxidation dyes and a layer of acrylic varnish, the two layers being juxtaposed one on the other. The weight per unit area of the acrylic lacquer layer varies from 1 to 10 g / m 2, and more particularly from 2 to 5 g / m 2. According to one variant, the sheet element is covered with a protective and detachable sheet. To do this, the edges of the sheet element and the protective sheet are glued together by means of a fixing means, in particular an adhesive, which can be produced by any type of method, in particular by heat sealing. Thus a good cohesion is ensured between the protective sheet and the sheet element. Advantageously, the protective sheet is opaque to UV for better protection. According to another variant, the sheet element may be covered by another means of protection, namely a hermetic package, defining above the element a space without oxygen (under vacuum or inert atmosphere). As indicated above, the substrate comprises at its surface one or more oxidation dyes. The oxidation dyes may be chosen from one or more oxidation bases optionally combined with one or more couplers. Preferably, the oxidation dyes comprise at least one oxidation base and at least one coupler.

The oxidation dye (s) may be present on all or part of the surface of the substrate. Thus, the surface of the substrate may be completely or partially covered by a layer containing one or more oxidation dyes. Preferably, the oxidation dye (s) are deposited on a portion of the surface of the substrate and represent patterns which, after contact with the keratinous fibers and the aqueous oxidizing composition, will make it possible to produce the colored patterns on said fibers. In other words, the oxidation dye (s) are deposited in the form of patterns on the surface of the substrate. Thus, the surface of the substrate comprises one or more oxidation dyes arranged in one or more particular geometrical forms, called units, which, after reaction with the aqueous oxidizing composition, lead to obtaining colored patterns on said fibers. The pattern or patterns have a shape that can be arbitrary and in particular geometric. Thus, the dye (s) are present on a part of the surface of the substrate and represent patterns having the desired shape. The substrate may comprise on the face opposite to the face carrying the oxidation dye (s) a copy of the pattern (s) having the desired shape. The realization of these patterns on the opposite side makes it possible to indicate the place where the oxidation dye (s) can then be deposited on the surface of the substrate. Such an embodiment subsequently makes it easier to place the substrate on the keratinous fibers where the pattern is to be made.
    [0022] Alternatively, such patterns are made on the surface of the substrate prior to pretreatment so as to subsequently deposit the oxidation dye (s) directly onto the patterns. In other words, the patterns that one wishes to obtain on the keratinous fibers can be made in advance on the surface of the substrate to be pretreated. In both cases, the production of patterns on the surface of the substrate to be pretreated or on the surface opposite the pretreated surface is all the more advantageous when the substrate used is transparent.
    [0023] In particular, the patterns can be printed in advance on the substrate. The substrate may further comprise at its surface one or more alkaline agents. In other words, the substrate may be pretreated with a dye composition comprising one or more oxidation dyes and one or more alkaline agents. The alkaline agents may be chosen from carbonates, alkanolamines such as mono-, di- and triethanolamines and their derivatives, oxyethylenated and / or oxypropylenated ethylenediamines, mineral or organic hydroxides, and alkali metal silicates such as metasilicates. sodium, amino acids of basic preferences such as arginine, lysine, ornithine, citruline and hystidine, and the compounds of formula (I) below: R a b N - W- NRRC d in which: - W is a divalent (C 1 -C 8) alkylene group, preferably propylene, optionally substituted in particular with a hydroxyl group or a C 1 -C 4 alkyl radical; Ra, Rb, R, and Rd, which are identical or different, represent a hydrogen atom, a Ci-C4 alkyl radical or a hydroxyalkyl radical. The inorganic or organic hydroxides, particularly the mineral or organic hydroxides, are preferably chosen from: the hydroxides of an alkali metal, ii) the hydroxides of an alkaline earth metal, such as sodium or potassium hydroxides, iii) the hydroxides of a transition metal, such as the hydroxides of Group III metals, IV, V and VI, iv) hydroxides of lanthanides or actinides, quaternary ammonium hydroxides and guanidinium hydroxide.
    [0024] The hydroxide may be formed in situ such as, for example, guanidine hydroxide by reaction of calcium hydroxide and guanidine carbonate. In particular, the alkaline agents used are solid in the dry state.
    [0025] In a first variant of the invention, the alkaline agents are solid before use in the dyeing composition, and are preferably selected from carbonates, mineral hydroxides such as hydroxides or soluble silicates of sodium or potassium.
    [0026] In another variant of the invention, the alkaline agents are chosen from alkanolamines, in particular mono-, di- and triethanolamines. The agent (s) alkali (s) may be present in a content ranging from 0.01 to 20% by weight, relative to the total weight of the treatment layer of the surface of the substrate. The alkaline agent (s) may be present in a content ranging from 0.01 to 20% by weight, based on the total weight of the surface treatment coloring composition of the substrate. The coloring composition may be aqueous or anhydrous.
    [0027] When the coloring composition is aqueous and contains one or more alkaline agents, the pH is preferably from 7.5 to 13, more preferably from 8 to 12, and most preferably from 8 to 11. The surface treatment coloring composition the substrate may also comprise one or more antioxidant active agents, preferably solid before use in the dyeing composition, such as ascorbic acid, cysteine or sulphites. The substrate may also comprise one or more compounds capable of slowing down the oxidative condensation reaction, such as acids, and in particular citric acid. The active agent (s) may be present in a content ranging from 1 to 20% by weight relative to the weight of the oxidation dyes both with respect to the treatment composition and with respect to the surface layer after pretreatment.
    [0028] The coloring composition may contain one or more organic solvents. As organic solvent, mention may be made of monoalcohols or diols, linear or branched, preferably saturated, comprising 2 to 6 carbon atoms, such as ethyl alcohol, isopropyl alcohol, hexylene glycol (2- methyl 2,4-pentanediol), neopentyl glycol and 3-methyl-1,5-pentanediol, butylene glycol, dipropylene glycol and propylene glycol; aromatic alcohols such as benzyl alcohol, phenylethyl alcohol; polyols with more than two hydroxyl functions such as glycerol; polyol ethers such as, for example, monomethyl, monoethyl and monobutyl ethers of ethylene glycol or propylene glycol; and the alkyl ethers of diethylene glycol, especially C1-C4, such as, for example, monoethyl ether or diethylene glycol monobutyl ether.
    [0029] The element may also include at the surface of the substrate a deposit of one or more activators or catalysts. In particular, the substrate comprises a deposit of one or more metal salts in a content ranging from 1 to 20% by weight relative to the weight of the oxidation dyes.
    [0030] The substrate used in the dyeing process is pretreated with a dye composition containing one or more oxidation dyes. Preferably, the substrate is pretreated with a dye composition containing one or more oxidation dyes and one or more alkaline agents. The dyeing composition may be liquid or in the form of a powder, preferably a liquid. The dye composition deposited on the surface of the substrate may possibly result from successive treatments of the substrate with one or more oxidation dyes on the one hand, one or more alkaline agents on the other hand, and optionally one or more active agents as described above. As indicated above, the oxidation dyeing process uses an aqueous composition containing one or more chemical oxidizing agents. By chemical oxidizing agent is meant an oxidizing agent different from the oxygen of the air. Preferably, the chemical oxidizing agent (s) is (are) chosen from hydrogen peroxide, urea peroxide, alkali metal bromates or ferricyanides, peroxygenated salts, for example alkali metal persulfates, perborates and percarbonates, or alkaline earth metals, as well as peracids and their precursors.
    [0031] Even more preferably, the oxidizing agent (s) is (are) chosen from hydrogen peroxide, urea peroxide and alkali metal bromates or ferricyanides. This oxidizing agent is advantageously constituted by hydrogen peroxide and especially in aqueous solution (hydrogen peroxide) whose concentration may vary, more particularly from 0.1 to 50% by weight, and even more preferably from 0.5 to 20% by weight. by weight, better from 1 to 15% by weight relative to the oxidizing composition.
    [0032] Preferably, the oxidizing agents are chosen from hydrogen peroxide and / or persalts. Preferably, the aqueous composition also contains one or more alkaline agents, especially the alkaline agents as described above. The use of an aqueous oxidizing composition containing one or more alkaline agents during the dyeing process according to the invention makes it possible in particular to lead to a lightening effect on the treated keratinous fibers, which reinforces the visibility of the pattern (s). obtained with the oxidation dyes present on the surface of the substrate. This use is particularly advantageous for the coloring of dark or brown hair. The aqueous oxidizing composition may further comprise one or more coloring agents such as couplers. In this way, contacting the keratinous fibers, the pretreated substrate and the aqueous oxidizing composition containing one or more couplers will lead to various colorations since the coupler or couplers present in the oxidizing composition may react with the or the oxidation bases present on the substrate. The use of an oxidizing aqueous composition containing one or more couplers is advantageous because it makes it possible to limit the use of the number of substrates by varying the nature of the oxidizing composition while increasing the possible results in terms of color. The use of an aqueous oxidizing composition containing one or more couplers thus makes it possible to obtain a wide range of colors.
    [0033] According to one embodiment, the oxidation dyeing process consists in bringing the keratinous fibers into contact with the substrate comprising, at its surface, one or more oxidation dyes, and then applying to said fibers the aqueous composition containing one or more oxidation dyes. several oxidizing agents.
    [0034] In particular, the keratinous fibers are placed on the surface of the substrate carrying the oxidation dye (s), that is to say at the point where the surface of the substrate is covered by the oxidation dye (s), and the oxidizing aqueous composition is then applied to said fibers. The oxidation dyes are thus dissolved, react with the oxidizing agent and color the keratinous fibers. The oxidizing aqueous composition is in particular applied using an applicator, in particular a brush, or with the hands.
    [0035] According to this embodiment, after the application of the oxidizing composition, the locks of hair thus treated can be protected by a paper to protect the other locks that are not treated. According to another embodiment, the oxidation dyeing process consists in applying an aqueous composition containing one or more oxidizing agents to the keratinous fibers and then in applying to said fibers a substrate comprising at its surface one or more dyes of oxidation. In this mode, the order of application between the pretreated substrate and the aqueous oxidizing composition is thus reversed with respect to the previous embodiment. In this embodiment, the keratinous fibers are in particular placed on a support, for example the upper surface of a sheet of paper, the aqueous oxidizing composition is applied to said fibers and then the substrate pretreated with one or more oxidation dyes is then applied to said fibers. The oxidation dyes present on the substrate surface are thus dissolved, react with the oxidizing agent and color the coated keratinous fibers.
    [0036] According to this embodiment, the substrate pretreated with one or more oxidation dyes is applied to the keratinous fibers treated with the oxidizing aqueous composition in such a way that the surface containing the oxidation dye (s) is in contact with the fibers.
    [0037] This coloring process, hereinafter referred to as the "reverse coloring process", has the advantage of minimizing or even eliminating the problems of contamination occurring between the applicator serving to apply the oxidizing composition and the oxidation dyes originating from the substrate. Indeed, when the keratinous fibers are first laid on the pretreated substrate, the applicator used to apply the oxidizing composition is then in contact with the oxidation dyes from the pretreated substrate which react with the oxidizing agents. Once the application has been carried out, the applicator thus contains both oxidation dyes and the oxidizing aqueous composition, which has the consequence of creating a risk of contamination of the remainder of the oxidizing aqueous composition and of increasing the risks. to alter the coloring of the other keratinous fibers.
    [0038] In particular, when the applicator is a brush, its bristles contain oxidation dyes that have reacted with the oxidizing agents of the oxidizing composition. Therefore, the brush may alter the rest of the oxidizing composition since its bristles contain oxidation dyes.
    [0039] The reverse coloring method therefore avoids this problem of contamination because the applicator is not in contact with the oxidation dyes from the pretreated substrate. Thus the rest of the oxidizing aqueous composition is not contaminated by the applicator and the risk of discolouration is minimized. The reverse coloring method is therefore particularly advantageous. Preferably, the aqueous oxidizing composition used during the reverse coloring process additionally contains one or more alkaline agents. The substrate pretreated with one or more oxidation dyes may be applied to the keratinous fibers for a time ranging from 5 to 60 minutes, preferably from 10 to 30 minutes.
    [0040] The oxidizing aqueous composition may be applied to the keratinous fibers for a time ranging from 5 to 60 minutes, preferably from 10 to 30 minutes. The substrate and the aqueous oxidizing composition may be applied at ambient temperature (25 ° C.), possibly with a temperature rise of up to 60 ° C. At the end of the treatment, the human keratin fibers are optionally rinsed with water, optionally washed with a shampoo followed by rinsing with water, before being dried or allowed to dry. Preferably, the substrate is pretreated with a dye composition containing one or more oxidation dyes and one or more alkaline agents and the aqueous oxidizing composition contains one or more oxidizing agents and optionally one or more alkaline agents. The present invention also relates to a process for the preparation of the substrate as described above comprising depositing by a printing method a coloring composition containing one or more oxidation dyes on the surface of a substrate. In other words, the coloring composition is printed on the surface of a substrate to obtain a substrate containing at its surface one or more oxidation dyes. Preferably, the coloring composition comprises one or more oxidation dyes in a content ranging from 0.01 to 100% by weight, preferably from 1 to 50% by weight, better still from 5 to 40% by weight relative to weight. total of said composition. More preferably, the coloring composition comprises one or more oxidation dyes and one or more alkaline agents. According to one embodiment, the process for preparing the substrate consists of depositing the composition containing the oxidation dye (s) on the surface of a substrate covered with a deposit of an adhesive composition. This adhesive layer may cover all or part of the substrate. In particular, the adhesive layer may represent a pattern. According to one embodiment, the process for preparing the substrate as described above consists in partially depositing on the surface of a substrate, by a printing method, a coloring composition containing one or more oxidation dyes. According to this embodiment, the oxidation dye (s) are deposited as one or more patterns on the surface of a substrate. In particular, the patterns may be squares, circles, ovals, ellipses, triangles in the form of solid patterns or lines surrounding these patterns. They can also be thick or thin lines, straight, curved, line crossings, representing letters, stylized designs or geometric patterns. They can also be dashed lines or dots. The printing method for depositing the composition on the surface of a substrate may be a screen printing method, a flexographic method, an offset process, or a printing method using an ink jet printer or a printer. laser. Preferably, the method of preparing the substrate comprises depositing a composition containing one or more oxidation dyes by screen printing or by a printing process using an ink jet printer. More preferably, the composition containing one or more oxidation dyes is printed on the surface of the substrate by means of an ink jet printer.
    [0041] The composition containing the oxidation dye (s) may be liquid or may be in the form of a powder. When the method of preparation is to use a printing method using a laser printer then the composition containing the oxidation dye (s) is in powder form. According to one embodiment, the process for preparing the substrate consists in depositing on the surface of a substrate a composition containing the oxidation dye (s) and then heating said surface to fix the powder. Preferably, the surface of the substrate is partially heated to create one or more patterns on the surface. According to another embodiment, the process for preparing the substrate consists of depositing the composition containing the oxidation dye (s) on the surface of a substrate, then removing or rendering ineffective in some parts all or part of the dyes of the substrate. 'oxidation. In this way, this method makes it possible to lead to the production of one or more patterns on the surface of the substrate.
    [0042] The step of partially removing the oxidation dye (s) can be achieved by scraping, buffering, blowing, suctioning or using an adhesive or wet surface where it is desired to remove the oxidation dye (s).
    [0043] The step of rendering all or part of the oxidation dyes on the surface of the substrate ineffective can be carried out by means of chemical transformation, for example oxidation or reduction, or by covering a protective compound .
    [0044] Furthermore, the method of preparing the substrate may further comprise a step of applying a starch film to enhance the strength of the substrate and improve the deposition of the oxidation dye (s) on the surface of the substrate. The starch film may be thin, of the order of 2 g / m 2, or thick, of the order of 70 g / m 2. The substrate thus pretreated according to the preparation method according to the invention preferably dries in a period ranging from 5 minutes to 120 minutes, preferably from 5 minutes to 90 minutes, more preferably from 1 minute to 60 minutes, and more preferably 5 minutes. at 60 minutes. Advantageously, in this embodiment by printing the substrate is a sheet element.
    [0045] The invention also relates to a sheet element as described above which is pretreated at its surface by a composition comprising one or more oxidation dyes as described above. The sheet element is thus completely or partially covered at its surface by one or more oxidation dyes. The sheet element has at its surface one or more oxidation dyes. In particular, the oxidation dye (s) has been printed on the sheet element. The sheet member may be made from a nonwoven material of fibers, especially a cellulose nonwoven or a derivative thereof. In particular, the sheet element may be a kraft type paper which has the advantage of being well printed and leading to precise patterns. Indeed, the colored patterns obtained on the keratin fibers do not drool following the application of the aqueous oxidizing composition. The sheet element may be a plastic sheet which has the particular advantage of restoring the power of the coloration which leads to patterns whose coloring is powerful. In addition, the plastic sheet does not absorb the water present in the aqueous oxidizing composition which makes it possible not to create dry areas under the keratinous fibers during the application of said composition.
    [0046] According to a first advantageous embodiment, the sheet element is a plastic sheet covered with a thin layer of paper, and in particular with a thickness of less than 50 μm, and more preferably less than 30 μm, paper type. cigarette or a layer of paper that can disintegrate in the presence of water, toilet paper type, a thin layer of hydrophilic material such as cellulose or a hydrophilic silica. According to this embodiment, the thin paper layer allows rapid drying and prevents the coloration from drooling following the application of the aqueous oxidizing composition. In addition, the paper layer beneath the thin paper absorbs little or no oxidation dyes from the sheet element due to its small thickness. The coloration is therefore well restored by the thin paper layer on the keratinous fibers, which leads in particular to sharp colored patterns. In addition, the sheet element according to this embodiment makes it possible to minimize the dry areas under the keratinous fibers. In the case where a support formed of a layer of paper, preferably little or no absorbent covered with a layer of paper capable of disintegrating in contact with water, is used: the layer of crumbly paper (thickness which can range from 10 2001.1m) allows a fast drying and prevents the color does not drool following the application of the aqueous oxidizing composition. In addition, the layer of paper underneath the friable paper does not absorb or little or oxidation dyes from the sheet element due to its small thickness. The coloration is therefore well restored by the thin paper layer on the keratinous fibers, which leads in particular to sharp colored patterns. In addition, the sheet element according to this embodiment makes it possible to minimize the dry areas under the keratinous fibers. In the case where a support formed of a layer of hydrophilic material is used: the layer of hydrophilic material is typically 5 to 2001.1m thick, which allows rapid drying and prevents the color from drooling following the application of the aqueous composition. This results in particular sharp colored patterns. According to a second advantageous embodiment, the sheet element is a microalveolar sheet, that is to say perforated by holes which are spaced from each other by a plastic material.
    [0047] Thus the oxidizing composition is housed in the holes of the substrate which will better restore the power of direct dyes on keratin fibers after application of the aqueous composition. The holes are at the surface of the sheet element to a thickness of 10 to 90% of the thickness of the sheet. According to this embodiment, the sheet element also has the advantage of being well printed, better rendering the coloring by leading in particular to patterns colored in a powerful way, not to absorb too much water from the aqueous composition and to minimize the risk that the color does not drool which leads to precisely colored patterns on the keratin fibers. The following examples serve to illustrate the invention without being limiting in nature.
    [0048] EXAMPLE Example 1: An ink jet printer is used. The cartridge is filled with a dye composition containing 30% by weight of 1-methyl-2,5-diaminobenzene. The dye composition additionally contains an alkaline agent in an amount such that the pH of the composition is equal to 9.
    [0049] A pattern is printed on a plastic sheet and then reprinted so that its surface is treated with the dye composition. The amount of the dye composition is 3 mg / cm 2 and 1 mg / cm 2 after drying.
    [0050] The plastic sheet is then cut into a rectangular shape 18 cm long and 5 cm wide. The plastic sheet is protected by a second plastic sheet. An aqueous oxidizing alkaline composition is prepared by mixing weight for weight, at the time of use, the composition sold under the name Oxydant Riche INOA 30 volumes and the alkaline composition based on 10% by weight of monoethanolamine.
