An object of the present invention is to provide a coating composition having excellent low-temperature short-time curability and satisfactory pot life (pot life), which makes it possible to obtain a cured coating film having an excellent finished appearance. The present invention provides a coating composition comprising a secondary hydroxyl group-containing acrylic resin comprising 20-50% by mass of a secondary hydroxyl-containing polymerizable unsaturated monomer (a) and 50-80% by mass of other polymerizable unsaturated monomers. A copolymer of monomer components of a saturated monomer (b); a polyisocyanate compound (B); and an organometallic catalyst (C) comprising a metal compound (C1) and an amidine compound (C2), wherein the metal is selected from zinc, tin , zirconium, bismuth, lead, cobalt, manganese, titanium, aluminum and molybdenum. |
