Patent ID: 7767738

Claim:
A composition comprising a blend of: (a) a resin blend of a polycarbonate resin and a cycloaliphatic polyester resin, said cycloaliphatic polyester resin comprising the reaction product of an aliphatic C 2 -C 12 diol or chemical equivalent and a C 6 -C 12 aliphatic diacid or chemical equivalent, said cycloaliphatic polyester resin containing at least about 80% by weight of a cycloaliphatic dicarboxylic acid, or chemical equivalent, and/or of a cycloaliphatic diol or chemical equivalent; (b) from 1 to 30% by weight of an impact modifying component comprising an amorphous resin having a refractive index from about 1.51 to about 1.58, said impact modifier enhancing the impact strength of molded composition as compared to a molding composition absent said impact modifier; and (c) from 0.0001 to 7 percent by weight of mica flakes for imparting a desired visual effect, wherein the composition is a miscible blend and comprises the polycarbonate and the cycloaliphatic polyester resin in amounts such that the index of refraction of the blend matches the index of refraction of said impact modifier to produce a transparent or translucent composition surrounding said flakes.
