Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a photocatalyst bearing printed matter whereon a photocatalyst is borne firmly, of which a design printed part hardly discolors and can be maintained clearly and which decomposes harmful substances such as an offensive smell constituent and can keep a comfortable indoor environment, and a manufacturing method thereof. SOLUTION: The design printed part 35 is formed on the upper side of a base material 31 selected from wood pulp paper or Japanese paper, woven or nonwoven fabric of chemical or vegetable fibers, knit or warp yarns. The photocatalyst bearing layer 39 is formed of transparent ink for printing containing photocatalyst particles prepared by covering partially the surface of a photocatalyst with ceramic inactive as the photocatalyst, so that it covers the whole surface of the design printed part 35. A thermally foamed embossed indentation is formed on the surface side having the design printer part 35 as occasion demands. |
