A photocatalyst layer is transferred onto the surface of an unsaturated polyester resin layer at the same time as forming a film, and an antifouling polyester decorative board capable of maintaining good photocatalytic degradation performance over a long period of time is obtained. . A decorative plate based on a film forming method, wherein a photocatalyst transfer film coated with a photocatalyst-containing composition and an inorganic primer is used as the film. The coating thickness of the photocatalyst-containing composition is 0.05 to 1.0 μm in the dry state, and the coating thickness of the inorganic primer is 0.2 to 1.5 μm in the dry state. The average particle size of the photocatalyst is preferably less than 0.3 μm. [Selection figure] None |
