<p>A photocatalytic titanium oxide coating composition which comprises (a) fine titanium oxide particles having photocatalytic activity, (b) either particles of an inorganic compound other than titanium oxide or organic compound particles which upon burning change into the inorganic compound particles, (c) a binder, and (d) a solvent, and in which the inorganic compound particles have an average particle diameter in the range of 0.1 to 1.0 νm and larger than that of the fine titanium oxide particles and are contained in an amount of 0.5 to 7 wt.% based on the fine titanium oxide particles. By applying this coating composition to a substrate surface, a thin film can be formed which retains high photocatalytic activity and has no interference colors.</p> |
