Title:
OPTICAL MEMBER AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2020/202874
Kind Code:
A1
Abstract:
This optical member is provided with a light-transmitting member and a functional film covering the light-transmitting member. The functional film contains: photocatalyst particles which are activated by ultraviolet radiation; and a specific titanium oxide which is titanium phosphate or peroxotitanium. At least some of the photocatalyst particles form photocatalyst secondary particles 4. This method for manufacturing an optical member comprises a film formation step of forming, on a light-transmitting member, a functional film containing: photocatalyst particles which are activated by ultraviolet radiation; and a specific titanium oxide. The specific titanium oxide is titanium phosphate or peroxotitanium. At least some of the photocatalyst particles form photocatalyst secondary particles.
