Abstract
Disclosed is a finish paint composition having a hydroxyl group containing resin (A) comprising a hydroxyl group value of 80 to 220 mgKOH/g, a glass transition temperature of −50° or above but below 0° C., and 25 to 55 mass% of units of 4-hydroxybutyl (meth)acrylate origin, a hydroxyl group containing resin (B) with a hydroxyl group value of 80 to 220 mgKOH/g, and a glass transition temperature of 0 to 50° C., and a crosslinking agent (C) comprising polyisocyanate compound having isocyanate groups, wherein the proportions of hydroxyl group containing resin (A) and hydroxyl group containing resin (B) are, as a ratio of solid fraction masses, from 95/5 to 50/50, and the proportion of isocyanate groups of the crosslinking agent (C) with respect to the hydroxyl groups in total of the hydroxyl group containing resin (A) and the hydroxyl group containing resin (B), as the NCO/OH mol ratio, is 0.5 to 1.5.
