    摘要: A coating agent for hand painting application obtained by a urethane resin composition obtained by allowing a main agent (A) and a curing agent (B) to react. The main agent (A) containing: an isocyanate group-terminated prepolymer (b) having diphenylmethane diisocyanate bound to the termini of a polyol component (a) containing a long chain polyol (e) which contains at least a polyhydroxy functional product such as a trihydroxy or higher-hydroxy functional product and having a molecular weight of 200 or greater; and unbound diphenylmethane diisocyanate(c). The curing agent (B) containing: a crosslinking agent (g) obtained by a short chain polyol (f) having a molecular weight of less than 200; and a long chain polyol (h) having a molecular weight of 200 or greater.
