<p><P>PROBLEM TO BE SOLVED: To provide a resin composition which can give a film excellent in dimensional stability, mechanical properties, and surface flatness, and an oriented polyester film using the same. <P>SOLUTION: The resin composition contains an aromatic polyester A represented by formula (1) and an aromatic polyester B represented by formula (2) at a weight ratio of 50:50 to 95:5, where X in formulas (1), (2) is 1,4-phenylene or 2,6-naphthalenediyl. The oriented polyester film is made of the resin composition. In formulas (1), (2), X is 1,4-phenylene or 2,6-naphthalenediyl; R<SB POS="POST">1</SB>is ethylene; and R<SB POS="POST">2</SB>is 2-10C alkylene or 8-10C cycloalkylene. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
