Abstract:
A photocatalytic titanium dioxide coating composition comprising (a) finely-divided titanium dioxide particles exhibiting photocatalytic activity, (b) particles of an inorganic compound other than titanium dioxide, or particles of an organic compound convertible to particles of an inorganic compound on firing, (c) a binder, and (d) a solvent, characterized in that the particles of an inorganic compound have an average particle diameter which is larger than that of the finely divided titanium dioxide particles and falls within the range of about 0.2 &mgr;m to about 1.0 &mgr;m; the inorganic compound particles are substantially insoluble in the solvent; and the amount of the inorganic compound particles is in the range of about 0.5% to 7% by weight based on the weight of the finely divided titanium dioxide particles.
