PROBLEM TO BE SOLVED: To form a photocatalyst film having excellent transparency and photocatalytic activity on the surface of an organic substrate with high adhesion strength without causing substrate deterioration (choking) by the photocatalyst film. ;SOLUTION: A siliceous under layer is formed on an organic substrate by applying an under coating material containing a product of hydrolysis of an alkoxysilane (wherein the alkoxysilane is oligomer and/or contains fluorine type surfactant having a perfluoroalkyl group) dissolved in an organic solvent and then a photocatalytic film is formed on the under layer by applying a photocatalytic coating material containing ultrafine titanium oxide with 0.1 μm or smaller average particle diameter, a β-diketone, a titanate type or aluminum type coupling agent, and a product of hydrolysis of an alkoxysilane in an organic solvent.;COPYRIGHT: (C)1999,JPO
