Patent ID: 7297409

Claim:
A layered composition comprising: an upper layer consisting essentially of: (a) a polymer system consisting essentially of a cycloaliphatic polyester; and (b) 0.01 to 10% by weight of a low volatility hydroxyphenyl-triazine or -pyrimidine UV absorber that contains a 2,4,6-trisaryl-1,3,5-triazine moity and a free hydroxyl group, or that contains a 2,4,6-trisaryl-1,3-pyrimidine moiety and a free hydroxyl group or a mixture thereof; and (c) 0.01 to 10% by weight of a hindered amine light stabilizer; an intermediate layer consisting essentially of a polymer system of a cycloaliphatic polyester and optionally one or more materials selected from the group consisting of 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 polymeric substrate, wherein said cycloaliphatic polyester in the upper and intermediate layers has recurring units of the formula: wherein R 1 and R 2 are each a cyclohexylidene, and wherein said hindered amine light stabilizer comprises a substituted piperidine moiety or an oligomer substituted piperidine moiety, or has the formula: wherein n is on average greater than 9, and less than 12, by the formula: wherein n is on average greater than 4, and less than 7, by the formula: or a mixture comprising at least one of the foregoing hindered amine light stabilizers, and wherein the cycloaliphatic polyester in the upper and intermediate layers is poly-1,4-cyclohexane-dimethanol-1,4-cyclohexanedicarboxylate.
