FIELD: chemical industry, production of solutions for films formation on base of cellulose esters in particular and in production of manufactured fibrous and film materials. SUBSTANCE: solution allows to increase light- and heat-resistance of film cellulose triacetate due to the fact, that solution for formation has 8-10 mas % of polymer, 0.01-0.024 mass % of 1- [1'-methylbenzimidazolyl-2'] -3-methyl-5-[2'-(n-sulfamidophenyl)-5" -ethyl-3", 4"-thiodiazolyl] formazan and up to 100 mass % of mixture of methylenechloride with ethanol in volumetric ratio of 9 : 1. EFFECT: increased light- and thermo-resistance of films of cellulose triacetate. 1 tbl |
