    The invention relates to copy papers intended for making copies with them in the process of typewriting. Copier paper, made of paper substrate and coating applied to it, is known (it is an acid-reactive dye of a phenolic type. The coating of such paper as an acid-reactive dye contains a mixture of phenol-formaldehyde resin and metal salt pj, but this paper is not sufficiently high resistance to punching due to low surface durability and puncture resistance. The aim of the invention is to increase the resistance of paper to punching. by increasing surface strength and puncture resistance. The goal is achieved by the fact that, in a copying paper made from a paper substrate and coated on it, including an acid-reactive coloring substance of a phenolic type, an acid-soluble phenol-formaldehyde resin contains an acid soluble salt , preferably salt, in an amount of 9-12% by weight of absolutely dry deposits / g. Both the metal part and the acid resin are part of the same oil The soluble molecule and both constituents are capable of reacting to color in an oil solution. This can be achieved by using certain oil-soluble metal salts of phenol-formaldehyde resins. Such salts are obtained by replacing a portion of the protons of the phenol of the phenol-formaldehyde resin with certain metal ions, which results in the so-called metal resinate. According to the invention, the dye precursor is applied either on the same substrate as said acid reaction substance or on a separate substrate. The common solvent dp of the reactants is placed in the crushing polymer material, better in the microcapsules, and separated from one or both of the reactants when they are on a single base. In a paired system containing two substrates, the solvent is retained on one of the substrates either alone or together with one of the reagents, which either dissolves in or dissolves in the solvent. The content (in wt.%) Of the metal ions in the metal resins used varies with the metal and resin chosen. Zinc, aluminum, barium, cadmium, calcium, cobalt, copper (w), indium, magnesium (i), manganese (I), molybdenum, nickel, lead, sodium, strontium, tin can be used as cations of this salt. , titanium, vanadium or zirconium (IJ /). The choice of metal for metal resins as developers that are resistant to discoloration of prints with a chromogenic substance does not have a great deal of importance because all metal resins are good in this respect. Cations such as zinc, cadmium and zirconium give metal-modified resins with the highest intensity of the fresh impression. The preparation of metal salts used in the proposed paper consists in the reaction of an oil-soluble phenol-aldehyde resin, better than a pair of substituted phenol-formaldehyde novolac resin with the desired one. metal hydroxide or oxide. A water-soluble intermediate metal resinate can also be obtained by treating pitch ;, with a strong base, such as aqueous sodium hydroxide, to produce an aqueous solution of sodium resins, followed by treating the sodium resins solution with an aqueous solution of the desired metal salt, zinc chloride, and precipitating the desired resins. metal in this case zinc rubber. According to a known method, a melt of an oil-soluble phenol-aldehyde novolak is reacted with the desired metal carboxylate or enoltome. This method is shown in Example 1, where the carpet is melted and treated with zinc oxybenzoate powder to produce zinc resin plus benzoic acid. If acetylacetonate is used instead of zinc oxybenzoate, then zinc rubber is formed along with free; m acetylacetone in a hot melt reaction. In one embodiment of this method, the metal salt can be added to the phenol-formaldehyde dehydrogenated mixture during resin production. When acid catalyzing condensation of monomeric phenols and aldehydes, water and acid are usually distilled off from the reaction mixture during the reaction. The addition of a water-soluble acidic metal salt, such as zinc chloride, to the condensation reaction is carried out in distilled hydrochloric acid, while leaving zinc resins as the product of the reaction. In this process, monomeric metal phenols are condensed (for example, zinc phenol) with aldehydes to form the desired metal resins. Example 1. A mixture of 2 kg of p-phenyl phenol formaldehyde resin is heated together with 400 g of zinc oxybenzoate with stirring for 1 h in an atmosphere of helium at elevated temperature. The temperature is gradually increased from room temperature to 200-220 ° C for about 45 minutes, then the cooler is given to for another 15 minutes. At the end of the reaction, the hot paraphenolformaldehyde zinc is poured from the reaction vessel, allowed to cool and solidify. The hardened resin is crushed under water in a mortar and is obtained finely; a spread powder suitable for applying a fine coating on a paper sheet. The zinc content of this resins (after rejecting a small amount of oil-insoluble inorganic sludge contained in the reaction products) is 5 wt.%. Suspension with 30 wt.% Solids for coating paper. Prepared by mixing the following ingredients in dry and wet matter, wt.%, Respectively: Zinc modified resin Kaolin clay Silica gel Calcium carbonate Styrene-butadiene latex Starch glue The paper is coated with an air knife and dried passing for 12 seconds through a high-speed air oven at an average temperature of about 87.8 s. A printed sheet with a primed coating containing an oil solution of lactone, a violet crystal, and benzoyl-leuco methylene blue is combined with the said sheets to obtain a receiving-receiving pair of sheets. Prouty 2. t on paper sheets that already have a coating of oil-containing microcapsules glued to the sheet with starch glue. The copying sheet produced in this way is mated with a second sheet of paper, previously soaked in a 2% solution of lactone in alcohol, and dried, leaving a residue of it on it at the coated side of the copying sheet facing the second sheet. When writing on the uncovered side of the copy paper with a pencil, the tokopi written appears on the second sheet as a result of the transfer of the metal-modified resin oil from the coated surface of the copy sheet to the contents of the lactone sheet. PRI me R 3. A solution of a metal-modified resin is obtained by dissolving in 50 parts of 1,2,4-trimethylbenzene 10 parts of paraphenol-formaldehyde resin and a solution of 14.5 parts of zinc naphthenate in 25 parts of a low-volatile hydrocarbon solvent, dispersing the oil solution in an aqueous solvent to obtain droplets with an average diameter of about 3.5 microns. The solution is encapsulated and the resulting capsules are applied as a coating on paper using polyvinyl alcohol as a binder for 10 parts of the capsule. Sheets coated with a cap of a metal-modified resin are matted with a sensitized sheet and a receiving-pair of sheets is obtained. When typing and handwriting with pressure, on the uncovered upper surface of the transfer sheet coated with capsules with resin, paired with a sensitized receiving sheet, get intense blue prints on the receiving sheet. EXAMPLE 4 A self-pressure sensitive sheet, a separate sheet containing all the color-producing elements, namely a metal-modified resin, a chromogenic dye precursor, an isolated solvent capable of dissolving both reagents, is obtained by applying a suspension of modified metal of the resin from the example on the primed coating of sheets of industrial paper or by applying a metal-modified resin containing the capsules of example 3 directly onto a sensitized sheet of same example. The proposed copier paper has significantly improved indicators of surface strength and puncture resistance. Thus, the strength of the surface of a known copying paper is 25 units. (wp) according to the IHT method, whereas the surface strength of the proposed 89 "paper is AO-50 units. These units characterize the viscosity of the ink used at a given temperature multiplied by the lowest speed of the printing rollers, at which a noticeable detachment of particles is observed. The puncture resistance of the proposed paper obtained in example I, is 61.9 units, according to the IHT method, while the known paper has a puncture resistance of 57.7 units. according to the IHT method. Improving these indicators prevents sticking and clogging of the surface of the printing device and, therefore, increases the resistance of the paper to penetration - one of the important performance properties of carbon paper.
