Abstract
This invention relates to thermoplastic article having one or more decorative materials embedded therein which is obtained by applying heat and pressure to one or more laminates wherein at least one of said laminates comprises, in order, (1) an upper sheet material; (2) one or more decorative materials; and (3) a lower sheet material; wherein the upper and lower sheet materials are formed from a polyester/aromatic polycarbonate blend.
Claims35
A thermoplastic article having one or more decorative materials embedded therein obtained by applying heat and pressure to one or more laminates wherein at least one of said laminates comprises, in order, (1) an upper sheet material;
- (2) one or more decorative materials;
- and (3) a lower sheet material;
- wherein the upper and lower sheet materials are formed from a polyester/aromatic polycarbonate blend, comprising:
- (a) 1 to 99 weight % of a polyester comprising a diacid residue component selected from the group consisting of aliphatic or alicyclic dicarboxylic acids and/or aromatic dicarboxylic acids, wherein the aromatic portion of said aromatic dicarboxylic acid has 6–20 carbon atoms, wherein the aliphatic or alicyclic portion of said aliphatic or alicyclic dicarboxylic acid has 3–20 carbon atoms;
- and a glycol residue component comprising from 45 mole % to 100 mole % 1,4-cyclohexanedimethanol, and optionally, at least one additional aliphatic glycol having 2–20 carbon atoms;
- wherein the total mole percentages for the glycol component equals 100 mole %, and
- (b) 99 to 1 weight % of an aromatic polycarbonate;
- wherein the total combined weight percentage of polyester and polycarbonate in the polyester/polycarbonate blend equals 100 weight %.
