Abstract:
1. A coating composition comprising: a secondary hydroxy-containing acrylic resin (A), which is a copolymer of monomer components comprising 20 to 50% by mass of a secondary hydroxy-containing polymerizable unsaturated monomer (a) and 50 to 80% by mass of at least one other polymerizable unsaturated monomer (b); a polyisocyanate compound (B); and an organometallic catalyst (C) containing a metallic compound (C1) in which the metal is a member selected from the group consisting of zinc, tin, zirconium, bismuth, lead, cobalt, manganese, titanium, aluminum and molybdenum, and an amidine compound (C2), wherein the equivalent ratio (NCO/OH) of isocyanate groups in the polyisocyanate compound (B) to hydroxy groups in the secondary hydroxy-containing acrylic resin (A) is in the range of 0.8 to 1.8.
