Abstract: A photocatalytic coating composition comprising photocatalytic titanium oxide, silver, copper and a quaternary ammonium hydroxide. The photocatalytic coating composition may include a photocatalytic titanium oxide sol dispersed in a binder. Furthermore, a photocatalytic member includes a substrate having a surface coated with the photocatalytic coating composition. The photocatalyst coating composition can contain highly antibacterial silver by skillfully utilizing copper and a quaternary ammonium hydroxide, and accordingly can show an antibacterial effect not only in a dark place simply due to silver, but also a higher antibacterial effect in a conventional application of employing ultraviolet sterilization by concomitantly using the photocatalyst titanium oxide sol according to the present invention and an ultraviolet sterilizer.

Abstract: A photocatalytic titanium oxide sol presents antibacterial properties in a dark place, and, in particular, relates to a photocatalytic titanium oxide sol which is stable and causes no discoloration by light even though containing silver, and relates to a coating composition and a member using the same. The photocatalytic titanium oxide sol includes silver, copper and a quaternary ammonium hydroxide, may be dispersed in a binder, and may be coated on the surface of a substrate.
