Coating method and coated article

Abstract

Provided is a coating method, including the steps of: applying a coating composition including inorganic fine particles and fluororesin particles in an aqueous medium onto a material to be coated; drying the coating composition on the material to be coated to remove the aqueous medium, thereby forming a porous film formed of the inorganic fine particles, the porous film having the fluororesin particles therein and having voids; and applying one or more water-soluble substances selected from the group consisting of a water-soluble surfactant and a water-soluble polymer onto the porous film, thereby filling the one or more water-soluble substances in the voids of the porous film. According to the coating method, there can be formed a coated article having a coating film which exhibits the excellent effect for inhibiting the attachment of oil stains for a long period and from which, even if oil stains are attached, the oil stains can be easily removed by wiping or washing with water.
