Abstract:
The present invention addresses the problem of providing a coating composition which can form a coating film, said coating film being capable of exhibiting and maintaining excellent stain resistance for a long period of time from the early stage and, moreover, being highly tolerant to acids. As a means for solving this problem, provided is a coating composition which comprises at least one kind of organic resin (A) selected from the group consisting of a polyester resin, a fluororesin and an acrylic resin, and a copolymer resin (B) obtained by copolymerizing a mixture containing an amino group- or quaternary ammonium salt group-containing polymerizable unsaturated monomer (b1) with another polymerizable unsaturated monomer (b2), said coating composition being characterized in that: the solid content mass ratio (A/B) of the organic resin (A) to the copolymer resin (B) is 97/3-70/30; and, in the copolymer resin (B), the ratio of the amino group- or quaternary ammonium salt group-containing polymerizable unsaturated monomer (b1) is 40-90 mass% relative to the monomers constituting the copolymer resin (B).
