PURPOSE: A paint composition for plastics is provided to ensure film properties such as abrasion resistance, adhesion, and heat resistance, excellent scratch resistance and soft texture. CONSTITUTION: A paint composition for plastics comprises 30~55 weight% of polyester polycarbonate-mixed polyurethane resin, 2~20 weight% of hardener, 1~10 weight% of quenching agent, 1~15 weight% of anti-sagging agent, 0.5~2 weight% of photostabilizer, and 20~70 weight% of solvent. The polyester polycarbonate-mixed polyurethane resin is obtained by reacting polyol with diisocyanate in a molar ratio of 1.01~3 : 1 wherein the polyol is obtained by mixing polyester polyol with polycarbonate polyol in a weight ratio of 1:9 ~ 9:1.
