PHOTOCATALYTIC OXIDE COMPOSITION, THIN FILM, AND COMPOSITE

摘要

A composition comprising oxide particles having photo-catalytic activity, a solvent-soluble zirconium compound and a solvent. Preferably, the oxide particles having photo-catalytic activity are titanium oxide particles; the oxide particles have an average particle diameter of 0.005 to 0. 39 m; and the amount of the zirconium compound is in the range of 3 - 200 parts by weight, as ZrO2, per 100 parts by weight of the oxide particles. A composite of a film having a photo- catalytic activity with a base material is made by coating the base material with the above composition to form a film, and curing the film on the base material.
