PHOTOCATALYTIC COATING MATERIAL, METHOD FOR FORMING FILM BY USING THE SAME, AND COATED MATERIAL HAVING PHOTOCATALYTIC FUNCTION BY APPLYING THE SAME MATERIAL

摘要

PROBLEM TO BE SOLVED: To obtain a photocatalytic coating material excellent in response in visible light zone, to provide a method for forming a film by using the same and a coated material obtained by applying the coating material.

SOLUTION: The improved photocatalytic coating material containing titanium oxide fine particles and silica fine particles is characterized by containing (70/30)-(95/5) weight ratio of rutile type crystal structure to anatase type crystal structure of titanium oxide fine particles, having 0.01-0.05 μm mean particle diameter and (70/30)-(95/5) weight ratio of the titanium oxide fine particles to the silica fine particles.
