FIELD: chemistry.
SUBSTANCE: disclosed is a polymer dyed composition which contains high- or low-pressure polyethylene and a pigment - sarcinaxanthine yellow pigment preparation, obtained from Micrococcus luteus biomass in form of a product of its alkaline hydrolysis or extract of the product of alkaline hydrolysis of said biomass with a polar organic solvent, in amount of 5.0-20.0 wt %.
EFFECT: dyeing uniformity with low content of pigment in polyethylene concentrates, preservation of physical and mechanical properties of polyethylene, wider raw material base for producing microbial dyes and the range of dyed compositions.
