    Colored adhesive manufacturing method {Manufacturing method for adhesive}
    [5] The present invention relates to a method for preparing a colored adhesive, and more particularly to a composition comprising plasticizers and thickeners in a mixture of natural rubber latex and synthetic rubber latex, or a mixture of these and an acrylic tackifier in emulsion form. The present invention relates to a method for producing a colored adhesive obtained by adding a predetermined amount of colored dyes and pigments to a latex adhesive for albums prepared by mixing two to four stabilizers having different absorption wavelengths.
    [6] In general, as shown in FIG. 1, the pressure-sensitive adhesive 4 applied to the album sheet 2 does not have a special color, and is manufactured by applying the colorless pressure-sensitive adhesive 4 to a white paper 6. There is a situation.
    [7] The album mount 2 is monotonous in color, so that the color of the album sheet is coated by a separate printing, dyeing or electrodeposition technique on the surface of the original paper 6 to improve the color.
    [8] However, there was a problem that the production cost of the album mount is increased due to an increase in the process and work time for separately coloring the original sheet to produce such a colored album sheet.
    [9] In addition, after a separate color is applied to the base paper, the adhesive is applied, so that the ink of a predetermined color applied between the base paper and the adhesive lowers the adhesive strength of the adhesive and the base paper, and thus the adhesive is easily peeled off from the base paper and damaged, thereby obtaining a high-quality product. When the white translucent album adhesive is applied to the base paper overlaid with a predetermined color, the color of the applied portion is passed through the adhesive and observed, resulting in a difference between the original color and the color seen by the viewer. There were various problems such as poor quality.
    [10] The present invention has been made to solve the above problems, by producing a pressure-sensitive adhesive applied to the surface of the base paper colored to obtain the same effect as applying a predetermined color to the base surface only with the color of the pressure-sensitive adhesive applied to the surface of the base paper The purpose is to obtain a colored pressure-sensitive adhesive.
    [1] 1 is an exemplary view showing an album sheet coated with a pressure-sensitive adhesive.

    [11] Hereinafter, the present invention will be described in detail.
    [12] First, the basic composition of the present invention, the method for producing a colored adhesive according to the present invention is a mixture of a natural rubber latex and synthetic rubber latex, or a mixture of a mixture of these and an acrylic tackifier in the form of an emulsion in a composition comprising a plasticizer and a medium In the adhesive which mixed 2-4 types of stabilizers with different ultraviolet absorbing wavelengths;
    [13] To the pressure-sensitive adhesive is added a pigment mixed in a predetermined ratio of the dye and pigment, characterized in that the ratio is 0.1 to 0.4% by weight.
    [14] Hereinafter, the present invention will be described in detail with reference to the preferred embodiments so that those skilled in the art can easily practice the present invention.
    [15] Natural rubber latex and synthetic rubber latex are used as the main raw materials for pressure-sensitive adhesives.Increasing the amount of natural rubber latex improves the adhesion and physical properties. Compared with natural rubber latex, adhesiveness and physical properties are reduced.
    [16] In the present invention, the amount of natural rubber and styrene-butadiene rubber latex is prepared by mixing 65-85% and 15-35%, respectively, but is not limited thereto.
    [17] In order to reinforce the adhesive properties of the pressure-sensitive adhesive for the album to the latex, a tackifier emulsified in acryl and matargyl series is used in the range of 5 to 15% by weight with respect to the rubber composition, and the mixture of the rubber latex has a low viscosity To increase their viscosity, a midpoint agent is added. It is added within 3% by weight relative to the mixture of this rubber latex.
    [18] As the middle agent is added, the viscosity of the mixture of the rubber latex is increased to generate bubbles due to the stirring of the mixture. The bubbles generated in this way stay in the mixture for a long time, it is impossible to apply a uniform pressure-sensitive adhesive, the silicone antifoaming agent was added to the mixture in the range of 1 to 3% by weight.
    [19] In addition, in order to control the peeling characteristics of the adhesive for the album mount, a phthalic plasticizer was added to improve the peeling feeling, and it should be added in the range of 10 to 20% by weight.
    [20] In addition, antioxidants and ultraviolet absorbers are added within 10% by weight to prevent photochromic and thermochromic properties of the adhesive.
    [21] The pressure-sensitive adhesive prepared by adding various additives as described above is milky white, and when the dye of a predetermined color formed by mixing a dye and a pigment is added within 0.1 to 0.4% by weight, the practitioner can obtain a pressure-sensitive adhesive. It is.
    [22] When the pressure-sensitive adhesive prepared as described above is applied to the base surface, a colored album sheet having a predetermined color can be obtained.
    [23] According to the pressure-sensitive adhesive formed by the addition of colored pigments as described above, when the color is formed by the pressure-sensitive adhesive itself, it is possible to easily obtain a high-quality album sheet having a color.
    [24] In addition, when the colored album sheet is produced using such an adhesive, a separate process of coloring the sheet is unnecessary, thereby reducing the overall work time for producing the album sheet, thereby reducing the cost of the album sheet. It is possible to obtain useful effects such as high quality album mount with beautiful appearance.
