STAINPROOF PRINTING SHEET AND MANUFACTURING METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a stainproof printed sheet which shows high discoloration/ fading proofness and self-cleaning properties and can be used outdoors for a long time. SOLUTION: This stainproof printing sheet includes a sheet-like base material (this material may be formed of a base sheet such as a fibrous cloth and a resin-coated layer), a outermost face dirt-proof layer containing a photocatalytic substance and an intermediate protecting layer which is formed between the former two and protects the base material and a printed image against an action by a photocatalytic substance. In addition, the printing sheet has an image printed on the surface of the base material or has a transparent resin layer formed between the base material and the intermediate protecting layer or has an image printed on the transparent resin layer whose image-printed face is positioned opposite to the base material.
