Description

The invention relates to the preparation of colored polymer compositions based on copolymers of styrene with acrylic acid. These compositions are suitable for the manufacture of organic light filters in optical devices, for protection of photo circuits, for use in stained glass windows of buildings, in antireflection screens of televisions and windshields of automobiles, etc. A known polymeric composition, including, mac.ch .: styrene copolymer with acrylonitrile 100, d, w-bisethylhexyl polydiethylene glycol phthalate dibutyl phthalate 5-12 and organic thrasher 1130-1tOO 1. The composition has good performance properties. One | But it is unpainted and cannot be used to make organic color filters. Closest to the present invention is a polymer composition, including, wt.h .: styrene copolymer with ac | 5ylonitrile 100, organic dye 0.1-0.28 and organic solvent 900. The dyeing components of the composition are the main dyes - auramine, the main purple K and the main turquoise. From this composition, colored films with a high light transmission coefficient C-92 o) are prepared, suitable for use as optical film filters 2). However, the films obtained from these compositions fade quickly, have low light resistance and significant brittleness. Under severe operating conditions, for example, under the action of light radiation (after 10 hours of UV irradiation J, the compositions fade to 9P-60 and break. This reduces the reliability and service life of film materials and significantly limits their application. In particular, these films do not can be used in high-quality devices for optical and radio purposes. The purpose of the invention is to increase the fading resistance of the composition and improve the operational properties. The goal is achieved by the fact that the polymer composition and, including a styrene-acrylonitrile copolymer, an organic solvent and an organic dye, the organic dye contains malachite green, or basic bright green, or cationic olive, or cationic red 2C, or cationic.
