FIELD: chemical industry, technology of organic compounds. SUBSTANCE: invention proposes solution that has, wt.-%: cellulose triacetate 8-10; oligoazomethine (molecular mass is 1 500 Da) that is a product of polycondensation of ortho-methyl-meta-phenylenediamine and benzyl 0.06-0.18, and a mixture of methylene chloride with ethanol at volume ratio 9:1 up to 100. Invention ensures to protect cellulose triacetate films from photooxidative degradation effectively and can be used in production of artificial fibrous and film material made of complex and complex-mixed cellulose esters. EFFECT: improved quality and property of films. 1 tbl
