A coating composition which is comprised of annemulsion of a silicone resin, typically a water-insoluble,nsilanol group-bearing silicone resin dispersed in water,nand contains photocatalyst particles, typically titaniumnoxide forms a hydrophilic film having a water-drop contactnangle of no more than 60° when irradiated with UV-containingnlight. The composition eliminates the use ofnorganic solvents and has excellent dispersion and storagenstability. Films obtained by applying this coatingncomposition to the surface of substrates have excellentnweathering resistance and antifouling properties due to anself-cleaning effect arising from the photocatalytic actionnof the particles. |
