PURPOSE:To obtain the title composition excellent in pigment dispersion, flexibility, hardness, weathering resistance, stain resistance and chemical resistance, by mixing a resin composition formed by dissolving a reaction product of a polyester resin with an acrylic resin in a solvent with a specified curing agent. CONSTITUTION:A resin composition (A) is obtained by dissolving a reaction product obtained by reacting 95-5pts.wt. polyester resin of a hydroxyl number of 5-200KOHmg/g and a number-average MW of 500-10,000 with 5-95pts.wt. acrylic resin of a hydroxyl number of 5-200KOHmg/g and a number-average MW of 500-20,000 at 180-280 deg.C for 10min<=5hr and dissolving the reaction product in a solvent (e.g., toluene). 100pts.wt. (in terms of solid matter) component A is mixed with 5-50pts.wt. amino resin (B) as a curing agent, or 1 equivalent of the hydroxyl groups of component A is mixed with 0.5-0.2 equivalents of the isocyanate groups in an isocyanate resin as a curing agent.
