PROBLEM TO BE SOLVED: To obtain a coating composition excellent in coating film performances such as processability, coating film hardness, blocking resistance and weather resistance and capable of forming uniform coating films which look like the citrus skin. SOLUTION: This coating composition comprises 100 pts.wt. of a resin component comprising (A) 20-80 pts.wt. of a polyester resin having a number-average mol.wt. of 2,000-18,000, a glass transition temperature of -20 deg.C to <5 deg.C, and a hydroxyl group value of 5-60 mgKOH/g, (B) 5-65 pts.wt. of a polyester resin having a number-average mol.wt. of 13,000-30,000, a glass transition temperature of 5-35 deg.C and a hydroxyl group value of 2-25 mgKOH/g, and (C) 15-35 pts.wt. of a melamine resin cross-linking agent, and (D) 1-20 pts.wt. of polybutylene terephthalate particles having an average particle diameter of 15-70μm. Therein, the component B has a larger number-average mol.wt. by >=1,000 than that of the component A. |
