FIELD: chemical industry. SUBSTANCE: dye composition included dye prepared from waste, result of manufacture of red alizarin (50 to 80 % ), or its admixture with dye prepared from waste that resulted from manufacture of green chrome anthraquinone alizarin taken in amount of 20 to 40 % and 20 to 40 % , respectively, or its admixture with dye derived from waste, result of manufacture of bright blue acidic anthraquinone taken in amount of 20 to 40 % and 20 to 40 % , respectively, or its admixture with dye obtained from waste as a result of production of green acidic anthraquinone alizarin taken in amount of 30 to 70 % and 10 to 20 % , respectively, or its admixture with dyes derived from waste resulted from manufacture of green chrome anthraquinone alizarin, acidic anthraquinone bright blue, and green acidic anthraquinone alizarin taken in amounts of 10 to 40 % , 10 to 20 % , 10 to 40 % , and 10 to 20 % , respectively, industrial carbon being the remainder (up to 100 % ). Dielectric strength of dye-colored phenol plastics accounted for 15.0 to 17.3 mV/m. EFFECT: highly durable dye composition. 3 tbl
