摘要： In a heat-curable coating composition containing an oil-free polyester resin and an aminoaldehyde resin as binder components, the improvement wherein(A) the materials for said oil-free polyester resin contain 40 to 75% by weight, based on the total weight of said materials, of at least one polyester-forming compound selected from the group consisting of(a) an aliphatic dibasic acid represented by the formula HOOC--CH.sub.2 --.sub.n COOH wherein n is an integer of 4 to 10 as a polybasic acid,(b) an aliphatic glycol represented by the formula HO--CH.sub.2 --.sub.n OH wherein n is an integer of 4 to 10 as a polyhydric alcohol, and(c) a lactone represented by the formula ##STR1## wherein n is an integer of 4 to 10, (B) the entire polybasic acid components of the polyester resin contain at least 10%, based on the total weight of said polybasic acid components, of an alicyclic polybasic acid or its anhydride, and(C) the polyester resin has a hydroxyl value of 20 to 95.
