PROBLEM TO BE SOLVED: To provide various types of resins and purposes thereof, obtained by using a low molecular weight polyester resin which can suitably elasticize a resin and can be used for various purposes.;SOLUTION: A coating composition contains a polyester resin (A) and a curing agent (B). The polyester resin (A) is obtained by polymerizing a monomer composition containing 10 to 90 mass% of a linear dicarboxylic acid and/or diol having at least 8C (I), 5 to 80 mass% of a branched dicarboxylic acid and/or diol having at least 4C (II-1), and/or 2 to 40 mass% of at least one polyfunctional monomer (II-2) selected from the group consisting of polyols, polycarboxylic acids and hydroxycarboxylic acids having 3 or more functional groups. The polyester resin has a number average molecular weight of 500 to 5000 and is amorphous.;COPYRIGHT: (C)2012,JPO&INPIT
