ABSTRACT:
The present invention provides a new photocatalyst sheet in which the substrates coated with fluorocarbon resin are readily weldable mutually, and also of the high antifouling and water-repellant property by coating the outermost surface of film/fabric structure with fluorocarbon resin containing a photocatalyst and a photocatalyst sheet comprises a substrate (2), a first fluorocarbon resin layer (3) coated on said substrate (2), a second fluorocarbon resin layer (4) coated on said first fluorocarbon resin layer (3), and a third fluorocarbon resin layer (5) containing photocatalyst coated on said second fluorocarbon resin layer (4). The melting point of the first fluorocarbon resin layer (3) may be higher than the melting points of the second and the third fluorocarbon resin layers (4), (5).
