PHOTODESTRUCTION OF HETEROCYCLIC MONOAZODYES BASED ON 2-METHYL-1,3,4- TIADIOZOLE IN POLYMER MATRICES
Studies of light fastness of new heterocyclic monoazodyes of the thiadiazole series in polymer films based on cellulose acetobutyrate (ABC), polymethylmethacrylate (PMMA) and styrene-acrylonitrile copolymer (SAN-25) under conditions of accelerated light-aging are presented. Recommendations on the use of these dyes as filter ones are given.
