ABSTRACT:
The present invention provides a method for producing a ceramic dispersion composition, the method comprising the step of heating a mixture of a ceramic powder having a photocatalytic activity, a dispersant and a solvent at a temperature of about 70° C. or higher without substantially letting the solvent out of the reaction system. The ceramic dispersion composition can be used for providing a film showing a high hydrophilicity by light irradiation.
