摘要： A polyester-modified vinyl polymer comprising 50 - 3% by weight of a polyester component and 50 - 97% by weight of a polyvinyl component grafted on the polyester component, the polyester component having an oil length of 5 to 20%, an average molecular weight of 1,000 to 6,000, and an .alpha.,.beta.-unsaturated dicarboxylic acid component content of 1 to 5% by weight on the polyester component. The polyester-modified vinyl polymer is useful in a high-solid solvent type coating composition.
