Abstract:
Provided are a photocatalyst transfer film allowing a uniform and highly transparent photocatalyst layer to be transferred to the surfaces of various transfer base materials; and a production method thereof. The photocatalyst transfer film has, on a biaxially oriented polypropylene film, a photocatalyst layer containing a titanium oxide particle-containing photocatalyst, a silicon compound and a surfactant. The production method of the photocatalyst transfer film includes applying a photocatalyst coating liquid to a biaxially oriented polypropylene film; and performing drying. The photocatalyst coating liquid contains a titanium oxide particle-containing photocatalyst, a silicon compound, a surfactant and an aqueous dispersion medium.
