Patent ID: 7649050

Claim:
A two package type clear coating composition comprising a hydroxyl-containing acrylic resin (A) having a hydroxyl value of 100-200 mgKOH/g and a number-average molecular weight of 5,000-10,000, which is obtained by copolymerization of a monomeric mixture comprising an aromatic vinyl monomer and a monomer having cyclohexyl ring; a trifunctional hexamethylene diisocyanate isocyanurate compound (B); and a polyester polyol (C) having a hydroxyl value of 250-350 mgKOH/g and a number-average molecular weight of 350-550, which is obtained by esterification reaction of 1,3-popanediol with 1,4-cyclohexane dicarboxylic acid wherein the two package type clear coating composition contains, as non-volatile component, the hydroxyl-containing acrylic resin (A) within a range of 30-75 mass %; the trifunctional hexamethylene diisocyanate isocyanurate compound (B) within a range of 20-60 mass %; and polyester polyol (C) within a range of 3-30 mass %; based on 100 mass parts of total solid content of components (A), (B) and (C).
