ABSTRACT:
A weatherable composition comprising an upper layer that comprises an aliphatic polyamide resin and an additive composition comprising an hindered amine light stabilizer and a hydroxyphenyl triazine or pyrimidine UV absorber; an intermediate layer that comprises a polymer system compatible with polymer in the upperlayer, 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.
