Artikel mit photokatalytischer Beschichtung

摘要

The invention relates to an article having a substrate and photocatalytic film covering the substrate. This film contains (1) a film-forming component including ZrO2 and SiO2 and (2) TiO2 crystals dispersed in the film-forming component. These ZrO2, SiO2 and TiO2 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.
