Photocatalytic coating material, photocatalytic composite material and process for producing the same, self-cleaning water-based coating compositions, and self-cleaning member

摘要

A self-cleaning water-base coating composition comprising the following ingredients (a), (b) and (c):(a) a silicone resin precursor composed of a water-based emulsion capable of forming a silicone resin film and/or a water-based emulsion capable of forming a fluorine resin and/or colloidal silica,(b) photocatalytic particles or photocatalytic sol, and(c) water,characterized in that the solid matter of the ingredient (b) constitutes 5% by weight or less of the total solid content of the coating composition.
