Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a polyester resin composition good in releasability even when molded using a mold planished with a polisher of No.8000 or greater and keeping its surface gloss intact even if exposed to high temperatures, and to provide a molded form made therefrom. SOLUTION: The polyester resin composition comprises a thermoplastic polyester resin and pentaerythritol-based compound(s), wherein the pentaerythritol-based compound is at least one selected from the group consisting of a pentaerythritol long-chain fatty acid ester polymer and pentaerythritol long-chain fatty acid-dibasic acid composite ester or its polymer. The molded form having the above-mentioned properties is obtained by molding this polyester resin composition. COPYRIGHT: (C)2006,JPO&NCIPI
