Abstract: The present invention provides a photocatalyst coated body which can realize a sufficient photocatalytic activity and adhesiveness with a substrate, without significantly impairing an appearance of a substrate, especially an exterior building material. The photocatalyst coated body has a structure including a substrate, an intermediate layer formed on the substrate, and a photocatalyst layer formed on the intermediate layer. The intermediate layer includes inorganic oxide particles having an average particle diameter of nanosize. The photocatalyst layer includes photocatalyst particles having an average particle diameter of more than 0 μm to less than 10 μm and inorganic oxide particles having an average particle diameter of nanosize. A sum of a film thickness of the intermediate layer and a film thickness of the photocatalyst layer is 0.3 μm or more to 1.5 μm or less.

Abstract: Provided is a method for readily forming a coating film on a surface of a substrate, that has an excellent applicability and is uniform or homogenous and has a good appearance. The present invention is a method for forming a coating film on a surface of a substrate. The method comprises the steps of: applying an aqueous coating composition to a surface of the substrate to form a liquid film, and drying the liquid film to form a dry film. The liquid film has a fine concave-convex shape including a plurality of convex parts and a plurality of concave parts. In the step of forming the dry film, the liquid film is dried to form the dry film in which the fine concave-convex shape of the liquid film is conserved.
