The present invention provides a titanium oxide dispersion, which has excellent dispersibility and dispersion stability, and can form a photocatalyst coating film that exhibits rapid and excellent photocatalyst ability by coating and drying.nn n n The titanium oxide dispersion liquid of the present invention contains titanium oxide particles (A) supporting a transition metal compound, a dispersant (B) containing polyacrylic acid or a salt thereof, and a solvent (C). The polyacrylic acid or a salt thereof in the dispersant (B) is preferably a polyacrylic acid alkali metal salt. The weight average molecular weight of the polyacrylic acid or its salt in the dispersant (B) is preferably in the range of 1,000 to 100,000. |
