Abstract:
A coating composition comprising a binder component consisting of(A) hydroxyl group-containing polyester resin having a number average molecular weight of 3,000-15,000, glass transition temperature of âˆ’25Â° C. to 15Â° C. and hydroxyl value of 5-95 mgKOH/g and (B) blocked polyisocyanate compound blocked with &egr;-caprolactam, the equivalent ratio of the blocked isocyanate groups in said blocked polyisocyanate compound (B)/hydroxyl groups in said polyester resin (A) being in the range of 0.7-1.2, and (C) resin fine particles with an average particle diameter of 8-70 &mgr;m which do not completely melt at the time of coating film curing, said coating composition containing 0.5-30 parts by weight of said resin fine particles (C) per 100 parts by weight of said binder component.
