Abstract
Photostabilizing properties of thermostable dyes and bulk-dyed polymer ic materials are considered. Photostabilizing dyes based on aroylenben ziwidazol derivatives used in polycaproamide and polyethylenterephthal ate are discussed. The photostabilizing action of the above dyes is re lated to their own photostability and is manifested through UV-shieldi ng, quenching of excited states of the polymer and inhibition of photo oxidative reactions.
