PROBLEM TO BE SOLVED: To provide a baking paint composition excellent in appearance, surface hardness, wear resistance and resistance to solvents, and to provide a coating finishing method using the baking paint. SOLUTION: The baking paint composition comprises (A) a vinyl based copolymer having a primary hydroxyl group, a phosphate group and 82-110°C of glass transition temperature (Tg), preferably composed of a vinyl monomer having a primary hydroxyl group and a vinyl monomer having a phosphate group and another vinyl monomer wherein the vinyl based copolymer is obtained by copolymerizing the vinyl monomer mixture containing 0.1-2 wt.% of the phosphate group containing monomer, and an amino resin (B), and the coating finishing method is characterized by forming a base coat on a substrate and then forming a top coat composed of the baking paint composition.
