A known method of obtaining pigments preparations intended for tinting vinyl varnish, according to the patent of the product No. 1134 735, consists in preparing a mixture of the following composition: 30% of the rosin pentaerythritol ester and 70% of the pigment, and then putting it on the heated shafts of two mills and kneading for 40 minutes. The obtained concentrate after crushing is used for dyeing varnishes intended for fiexographic and rotogravure printing. This method requires the use of very finely divided pigment powder, and long-term kneading or rolling of the preparation at the melting point of the carrier does not always give the intended color effect of the preparation and is a very energy-intensive process. Another method presented in British Patent No. 9ll5453 describes a method of preparing pigments by mixing a fine pigment in the form of an aqueous filter paste with methyl chloride, a copolymer of vinyl chloride and vinyl acetate, a plasticizer and the addition of polyvinyl acetate as a suspension stabilizer. It is completely ground and heated until the water evaporates. A pigment preparation is obtained in the form of granules with a size of 1-5 mm, while British Patent No. 915) 4 9318 recommends a method of obtaining pigment preparations, consisting in mixing aqueous pigment paste dispersed in a ball mill with polychloride latex. the vinyl or vinyl chloride copolymer with vinyl acetate, dilute the mixture with water to 5-Bf / d, and then coagulate the latex with the pigment by adding hydrochloric acid or inorganic salt, or by acidifying and boiling. The obtained coagulum is filtered, dried and ground to a powder. This method requires the use of acid-resistant or long-resistant equipment of high capacity due to the high water dilution of the reaction mass. According to the invention, the latex of the copolymer of vinyl chloride with butyl maleate is kneaded with an aqueous pigment paste containing an organic, inorganic pigment, carbon black and caustic pigments at the boiling point of water, and the resulting plastic mass of the preparation which spontaneously separates from the water layer, washed, dried and crushed into a powder. The ratio of the copolymer used dk of the dry pigment contained in the aqueous paste is 90-330: 10-tfO. By following the process according to the invention, it has surprisingly been found that by kneading the latex of a copolymer of vinyl chloride with butyl maleate from a coconut oil into a pigment paste, it forms an intrinsic coagulum at the boiling point of water that separates the slag from the water. 138 282/138 282 3 The advantage of the method according to the invention is the possibility of carrying out the entire preparation process in one process of dyeing in Wrotkom czaisie. The pigment mixed in the coagulum does not contain agglomerates, and the obtained pigment preparation contains, in a selected manner, a dispersed pigment, evenly distributed, evenly distributed, in vinyl varnishes, giving a tint of a pure shade and repeating colors. The polyvinyl chloride used for mass dyeing is dispersed in a short time, giving uniform reproducible dyeing. The examples below illustrate the method of carrying out the invention. Example 1 5 parts by weight of chloride copolymer latex are introduced into a zet kneader equipped with a heating jacket. vinyl with butyl maleate and 1'00 parts by weight of an aqueous copper phthalocyanine pigment paste - Form B containing 25 parts by weight of dry pigment and 2 parts by weight of anionic dispersant, then all mixed and heated to boiling. A coagull of copolymer and pigment is formed which separates from the aqueous layer in the form of a plastic mass. The separated water is poured until 100 parts by weight of water at 96 ° C are introduced into the kneader and all grinded in K5 mlmult, the water is removed and the washing is repeated several times until the water is colorless. The pigment preparation is then further kneaded until the water evaporates completely, then the heating is turned off, the quench introduces cold water into the heating mantle, the preparation is cooled and the kneader is turned on again to crush the preparation. The preparation is in the form of a powder, with a pigment content of 50%, which is used for dyeing vinyl lacquers and polyvinyl chloride in mass. Example II. Following the procedure described in Example 1, 100 parts by weight of an aqueous pigment paste containing 10 parts by weight of SAB-1 Black is mixed and kneaded with U 810 parts by weight of vinyl chloride copolymer latex with butyl maleinliate containing 910 parts by weight. of dry copdlliymer. After the pathetic pigment preparation is obtained, it is rinsed, dried and crumbled. A preparation is obtained in the form of a black powder with a 1-pigment content, used for tinting vinyl lacquers and polyvinyl chloride in the mass. Example III. Following the method described in Example I, 140 parts by weight of an aqueous pigment paste containing TH parts by weight of dry inorganic pigment BH iron is mixed and kneaded with 90 parts by weight of a copolymer of vinyl chloride copolymer with butyl butylate content of 310 parts by weight. parts by weight of the dry copolymer. After the plastic pigment plrepairite is thawed from the water, the preparation rinses, dries and crumbles. A pigment preparation is obtained in the form of a red-yellow pyoshik with a T-pigment content, which is used for dyeing vinyl varnishes and polyvinyl chloride. A patent process. A method of obtaining pigment preparations for the preparation of colored vinyl varnishes and for dyeing in polycMoride malsa. vinyl by suspending the pigment in a vinyl carrier, the latex of a copolymer of vinyl chloride with butyl maleate being kneaded; at the boiling point of the aqueous paste the pigments, and the resulting plastic mass of the preparation, which spontaneously separates from the water, is washed, dried and crushed into a powder, the quantitative ratio of the copolymer used to the dry pigment contained in the aqueous paste is 90M3O: 10- ^ TOi.
