COATING COMPOSITION, METHOD FOR FORMATION OF COATING FILM, AND ARTICLE HAVING THE COATING FILM

摘要

Disclosed is a coating composition comprising stannic acid (A), at least one compound (B) selected from the group consisting of ammonia, tetramethylammonium hydroxide and a water-soluble amine, water (C), and at least one component (D) selected from the group consisting of photocatalyst particles, an ultraviolet ray blocker, and an infrared ray blocker. When various types of coating films such as a photocatalyst coating film or an ultraviolet ray and/or infrared ray blocking coating film are formed using the coating composition, the coating films can have desired properties such as a photocatalytic activity or an ultraviolet ray and/or infrared ray blocking property and can be formed by a heating treatment at lower temperatures and in a simple manner. The coating composition has excellent storage stability.
