FIELD: coloring of plastics, film materials, synthetic threads; production of paint and varnish materials. SUBSTANCE: method involves treatment of inorganic carrier with hydroxide of alkaline metal followed by treatment with organosilicium amine. Then hydrogen chloride acid is added into reaction mixture till its amount is equamolar to amine amount. Sulfo dye (as its sodium salt) is grafted on thus treated carrier. Calcium chloride is added into reaction mixture, desired pigment is isolated and then it is dried. Ratio of components, wt.p. is as follows: inorganic carrier, 100; hydroxide of alkaline metal, 0.2-0.5; organosilicium amine, 0.3-3.0; direct or acid dye, 5-25; calcium chloride, 0.1-0.5. EFFECT: improved efficiency of the method. 9 cl, 1 tbl
