Abstract
A coating composition which comprises (A) a resin having a glass transition temperature of 50 to 120.degree. C., a number average molecular weight of 2,000 to 100,000, a hydroxyl value of 50 to 150 mgKOH/g and an acid value of 1 to 25 mgKOH/g, which is produced by copolymerizing 10 to 90 percent by weight of (a) a (meth)acrylic acid ester of a C.sub.1 to C.sub.12 alkyl alcohol, 10 to 50 weight % of (b) a first polymerizable double bond-containing and hydroxyl group-containing monomer, 0.1 to 10 weight % of (c) a polymerizable double bond-containing and carboxyl group-containing monomer, 0 to 20 weight % of (d) styrene, 0 to 20 weight % of (e) acrylonitrile and 0 to 10 weight of (f) a second polymerizable double bond-containing monomer, (B) at least one compound selected from the group consisting of a polyisocyanate compound having two or more unblocked isocyanate groups and/or blocked isocyanate groups in the molecule and an aminoplast resin, (C) a dispersing component of at least one inorganic oxide sol selected from the group consisting of an aluminum oxide sol, a silica sol, a zirconium oxide sol and an antimony oxide sol, wherein an amount of a nonvolatile matter of component (…
