<P>PROBLEM TO BE SOLVED: To provide a laminate having a visible light photocatalyst layer which shows sufficient photocatalytic action under an environment reduced in the amount of a spectral component with a wavelength of below 400 nm, for example, under an indoor environment or in a car compartment having ultraviolet cutting glass and has excellent transparency and prevents the deterioration of an organic base material. <P>SOLUTION: The laminate is composed of the organic base material, an intermediate layer provided on the organic base material and a photocatalyst layer provided on the intermediate layer. The photocatalyst layer is a layer formed from a visible light photocatalyst composition containing an oxide semiconductor (a) having visible light photocatalytic activity being nitrogen doped titanium oxide, a titanium compound (b) having a specific structure and a silane compound (c) having a specific structure. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
