[PROBLEMS] To provide a photocatalyst titanium oxide sol that exhibits antibacterial activity in dark places and that even when silver is contained, is stable without discoloration by light, and provide a coating composition and member utilizing the same. [MEANS FOR SOLVING PROBLEMS] There is provided a photocatalyst titanium oxide sol comprising silver, copper and quaternary ammonium hydroxide. Further, there is provided a photocatalyst coating composition having the photocatalyst titanium oxide sol dispersed in a binder. Still further, there is provided a member having a surface of base material coated with the photocatalyst coating composition. This photocatalyst titanium oxide sol has realized containing of highly antibacterial silver through ingenious use of copper and quaternary ammonium hydroxide. Thus, not only can antibacterial effects by silver alone in dark places be exerted but also, in conventional uses involving ultraviolet sterilization, etc., more effective antibacterial effects can be attained by the use of this photocatalyst titanium oxide sol in combination with an ultraviolet sterilizing device, etc.

Le problème à résoudre dans le cadre de la présente invention consiste à proposer un sol d'oxyde de titane photocatalyseur qui montre une activité antibactérienne dans les espaces sombres et qui, même lorsque de l'argent est contenu, est stable sans décoloration à la lumière, ainsi qu'une composition de revêtement et un élément l'utilisant. La solution proposée concerne un sol d'oxyde de titane photocatalyseur comprenant de l'argent, du cuivre et un hydroxyde d'ammonium quaternaire. En outre, on propose une composition de revêtement photocatalytique comportant ledit sol dispersé dans un liant. Encore en outre, on propose un élément ayant une surface d'un matériau de base revêtue de ladite composition. Ledit sol a pu contenir de l'argent extrêmement antibactérien par l'utilisation ingénieuse du cuivre et de l'hydroxyde d'ammonium quaternaire. Ainsi, non seulement les effets antibactériens de l'argent seul peuvent être exercés dans les espaces sombres, mais aussi, lors d'utilisations classiques mettant en jeu une stérilisation par ultraviolets, etc., des effets antibactériens plus efficaces peuvent être obtenus par l'utilisation dudit sol en combinaison avec un dispositif de stérilisation aux ultraviolets, etc.
