Abstract
The invention relates to an article having a substrate and photocatalytic film covering the substrate. This film contains (1) a film-forming component including ZrO and SiO and (2) TiO crystals dispersed in the film-forming component. These ZrO , SiO and TiO crystals respectively are in amounts of 25-60 wt %, 15-50 wt % and 25-45 wt %, based on the weight of the film. The article is improved in photocatalytic activity, abrasion resistance and chemical resistance by the provision of the film.
