MEMBER HAVING PHOTOCATALYTIC ACTIVITY AND MULTILAYERED GLASS

摘要

A member having high photocatalytic activity and multiple glass using the member are provided. A photocatalyst layer (TiO 2 ) is formed on the surface of a substrate (glass sheet) through the intermediary of a crystalline undercoat layer (ZrO 2 ), and no dead layer is substantially present between the photocatalyst layer and the undercoat layer. Also, provision of an amorphous layer between the substrate and the undercoat layer prevents peeling or defects between the photocatalyst layer and the substrate. In particular, by adjusting the thickness of each layer within a specific range, it is possible to obtain an article having a film configuration in which the optical feature of a reflection color, small variation of the reflectance, and a photocatalytic function are combined.
