a little

Vinyl acetate homopolymer or vinyl acetate copolymer with dialkyl maleinate, or vinyl chloride copolymer with vinyl acetate, or copolymer of butyl acrylate, methyl acrylate and methacrylic acid can be used as a film-forming polymer.

The by-product of the synthesis of isoprene rubbers used in the proposed composition is a transparent, non-dispersible oily liquid with a boiling point of 153 ° C, a self-ignition temperature of 272 ° C, and a flash point of 90 ° C.

8, the by-passed govagive, the by-product of the synthesis of isoprene rubbers is used as a universal dispersion medium that allows the use of achromatic pigments and dyes as in water, organic compound and organic solvent. This made it possible to expand the range of film-forming polymers used and the printed and ecgpatened Sooi.Ts ,, material (durable. Strength, elasticity, hardness, printing properties).

As the achromatic pigment, titanium dioxide, or zinc oxide, or kaolin can be used. Organic colorants and / or chromatic pigments can be used as colourants. The choice of colorant is determined by the desired color of the bumming coating. Green or blue phthalocyanine, light yellow, scarlet and others can be used.

The composition is prepared as follows. The achromatic pigment and dye are dispersed in a mixture of solvents and by-product of the synthesis of isoprene rubber in a bead mill for 0.5-1.0 h with a shaft speed of 1000 rpm to form a paste. The solution or dispersion of the polymer is then mixed with the resulting paste for 1 hour with a stirring speed of 50-100 rpm.

Cooked recipes are given in table 1 (examples 5-8 control).

The composition is applied to the polyethylene terephthalate film with one or two sides using a raster shaft or a wire squeegee. After applying the composition, the material is dried at a temperature of 80-170 ° C. Coating thickness 5-8 µm.

Properties of the composition and coating are given in Table 2.

For comparison, a known composition is prepared, wt.%:

Polymethyl methacrylate2.0

Kaolin6.0

Coumarin 0.07

Oksazil 1 perchlorate0,09

Diphenylamine1,2

Dichloroethane90,64

To prepare the composition, dichloroethane is introduced into an airtight container, then polymethyl methacrylate is dissolved in it, kaolin, coumarin 7, oxazine 1 and diphenylamine perchlorate are added. The composition is applied to a defatted polyethylene terephthalate film. The coating thickness is 5 microns.

Characteristics of the resulting composition and

The material manufactured with its use is also given in Table 2.

From the data given in table 2, it is clear that the proposed composition compared

0 with the known allows to increase the operational properties of the material: to increase the adhesion of the coating to the substrate and to significantly increase the elasticity of the coating (to increase the number of double kinks before the destruction of the coating), which leads to an increase in the service life of the material. - spmchi gyrial, not inferior in terms of its appearance and water resistance to the material,

0 obtained with a known composition, and allows a significant expansion of the color gamut of multilayer paper-like materials,

The output of the ratios of the components of the prevailed composition beyond the specified limits leads to a deterioration of the appearance (examples 6 and 8) or to a decrease in resistance to fracture, adhesion, hardness. In addition, a higher viscosity of the composition makes it possible to carry the bumming coating in one layer with the required thickness (5-10 μm).

The higher dispersion of the proposed composition ensures homogeneity of the bumming coating, which, in its

5 queue, prevents plucking when applying the paint layer.

The use of tinted paper-like materials using the proposed composition allows to reduce
