Abstract
Disclosed are antifouling material possessing excellent surface antifouling properties, particularly excellent antifouling activity against greasy stains and soils, a process for producing the same, and a coating composition and an apparatus for the antifouling material. The antifouling material comprises: a substrate; and an inorganic layer consisting essentially of an amorphous metal oxide, the inorganic layer containing an alkali metal and non-bridging oxygen in an amount effective in removing contaminants, derived from an exhaust gas, adhered on the surface of the inorganic layer by cleaning using running water alone to restore the diffuse reflectance of the surface of the inorganic layer to not less than 75% of the initial diffuse reflectance, the inorganic layer constituting the outermost fixed layer of the antifouling material.
