ABSTRACT:
A condensation polymerization of apolyhydric alcohol and a polybasic acid in a solvent is performed to give a polyester resin. The polyester resin and an unsaturated polybasic acid are polymerized to give a polyester resin intermediate of following formula (1) having a carbon-carbon double bond at one end. The polyester resin intermediate is polymerized with an acryl monomer to give an acryl-modified polyester resin composition. Due to the polymerization of the polyester resin intermediate having the carbon-carbon double bond and the acryl monomer, a paint including the acryl-modified polyester resin composition has advantages of a polyester resin and the acryl resin,in-line-formulae description="In-line Formulae" end="lead"?R—CH2—O—CO—CH═CH—X  (1)in-line-formulae description="In-line Formulae" end="tail"?wherein R represents a polyester polymer residue, and X represents a methyl or carboxylic group.
