Abstract
The present invention provides a stain-proof coating composition including silica fine particles (A), a nonionic surfactant (B), and a nonionic surfactant (C), wherein the nonionic surfactant (B) is at least one kind of nonionic surfactant (B) selected from the group consisting of an acetylenediol-based surfactant (b-1) and a polyoxyalkylene alkyl ether-based surfactant (b-2), the nonionic surfactant (C) is at least one kind of nonionic surfactant (C) selected from the group consisting of a vinyl-based polymeric surfactant (c-1) and a polyoxyalkylene fatty acid ester-based surfactant (c-2).
