This invention provides a paint composition which comprises a film-forming resin component comprising from 65 to 95 parts by weight of a hydroxyl-containing polyester resin (A) having a number average molecular weight of from 1,500 to 35,000, a glass transition temperature of from -30° C. to 60° C. and a hydroxyl value of from 3 to 100 mg KOH/g; and 5-35 parts by weight of a melamine resin crosslinking agent (B) which is a methylolated melamine resin whose methylol groups are alkyl etherified, at least 20% of the total number of methylol groups therein having been etherified with a C6-C12 alkyl group; and (C) 0.1 to 2.0 parts by weight, per 100 parts by weight of the total resin component, of a curing catalyst. The paint composition excels in popping resistance, and can form paint film of favorable hardness, formability, curability (solvent resistance) and adhesion.
