<P>PROBLEM TO BE SOLVED: To provide amorphous polyester resin excellent in heat and moisture resistance, with sufficient hardness and adhesiveness, when it is made into a coating film, in which high glass transition temperature is achieved despite that a biomass raw material is used, and to provide a resin composition using the same. <P>SOLUTION: A copolyester resin consists mainly of a dicarboxylic acid component and a glycol component, when all polycarboxylic acid components that compose the copolyester are 100 mole percent, naphthalenedicarboxylic acid is contained by 30 mole percent or more, and sebacic acid is contained by 30 mole percent or more, in the copolyester resin, and the resin composition for coating including the same. <P>COPYRIGHT: (C)2012,JPO&INPIT |
