Abstract
A coating composition contains: PA1 (i) a mixture of copolymers comprising (a) 20% to 80% by weight, in terms of the resin solid content, of at least one copolymer selected from the group consisting of silicon-containing copolymers and fluorine-containing copolymers comprising 40 to 60 mol % of fluoroolefin, 45 to 5 mol % of cyclohexylvinyl ether, 15 to 5 mol % of alkylvinyl ether, and 0 to 30 mol % of other comonomers, having an active hydrogen group and (b) 80% to 20% by weight, in terms of the resin solid content, of an acrylic copolymer resin having a solubility parameter greater by 0.5 to 1.5 than that of the copolymer (a) and having an active hydrogen group, and PA1 (ii) a curing agent having a solubility parameter greater by 0.5 to 1.5 than that of the copolymer (a).
