PHOTOCATALYTIC AGENT FLUID AND METHOD FOR FORMING PHOTOCATALYTIC AGENT FILM

摘要

PROBLEM TO BE SOLVED: To prepare a photocatalytic agent fluid whose coated areas can easily be distinguished from uncoated areas by visual observation and which can form a photocatalytic film on a predetermined area, and to provide a method for forming the photocatalytic film. SOLUTION: The photocatalytic agent fluid contains a metallic component as metal oxide fine particles which exhibit a photocatalytic action by irradiation with ultraviolet rays and at least one coloring component selected from the group consisting of an organic phosphor and an organic dye which are decomposable by irradiation with ultraviolet rays. Further, it is preferred that the metallic component is TiO2 fine particles having a particle diameter of 10-100 nm whose major component is of the anatase type.
