Abstract
A two package type clear coating composition which can form cured coating film excelling in all aspects of scratch resistance, acid resistance, stain resistance and finished appearance such as coated surface smoothness, 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 HMDI 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 Cdiol with dicarboxylic acid having cyclohexyl ring.
