Abstract:
1. A method for preparing a laminate which exhibits photocatalytic activity capable of decomposing triolein at a rate of 5 μg/cm 2 /day or more when irradiating UV rays in UV-A range at a strength of 3 mW/cm 2 under an atmospheric temperature of 25° C. and relative humidity of 70%, the method comprising the steps of: (a) coating a polymer resin film with a coating solution comprising an adhesive and then drying to form an adhesive layer; (b) subsequently coating the adhesive layer with a coating solution comprising a photocatalyst and then drying the coating solution to prepare a photocatalyst-supporting film which carries the photocatalyst layer on the polymer resin film via the adhesive layer, and (c) heat-pressing the photocatalyst-supporting film onto a surface of a metallic plate or a resin substrate at a temperature range from 100 to 200° C. to form an integral laminate.
