PROBLEM TO BE SOLVED: To provide a polyvinyl chloride resin base material overlaid with a photocatalytic layer, that is obtained by forming a photocatalytic layer on a polyvinyl chloride resin base material, shows a sufficient photocatalytic action and does not generate acetaldehyde derived from plasticizers. SOLUTION: This photocatalytic layer-overlaid polyvinyl chloride resin base material is formed by laying a cured product layer made when a curable ethylene-vinyl acetate copolymer is cured and a photocatalytic layer comprising a photocatalyst in the above order on top of a polyvinyl chloride resin base material. Preferably, an inorganic compound layer is interlaminated between the cured product layer and the photocatalytic layer. COPYRIGHT: (C)2009,JPO&INPIT
