ABSTRACT:
A weatherable composition comprising an upper layer that comprises a polymer system consisting essentially of a cycloaliphatic polyester resin, and an additive composition comprising an hindered amine light stabilizer and a low volatility, hydroxyphenyl triazine or pyrimidine UV absorber; an intermediate layer that comprises a polymer system consisting essentially of a cycloaliphatic polyester, and optionally, an additive composition comprising TiO2, dyes, pigments, and special effects additives; and a polymeric substrate, wherein the intermediate layer is disposed between and in intimate contact with the upper layer and the substrate. The composition finds utility in articles such as automotive parts.
