PURPOSE:To provide a coating compsn. which prevents sagging and bittiness during coating, baking, and curing and provides good finishing film performance, by incorporating a hydroxyl group-contg. resin and a particular alkylated melamine/formaldehyde resin. CONSTITUTION:A coating compsn. comprising a hydroxyl group-contg. resin (A) and an alkylated melamine/formaldehyde resin having a number-average MW of 2,000-5,000 and an amt. of active methylol groups per triazine nucleus of 0.2-1.5mol (B) so that the wt. ratio of the resins A to B is 50/50-95/5. n-Butylated melamine/formaldehyde resin, isobutylated melamine/formaldehyde resin, and the like are desirable because of a particularly significant effect as the resin A used. If necessary, colorants, solvents, surface modifiers, substances that impart weatherability, coatability modifiers, and the like may be incorporated properly in said coating compsn.
