AQUEOUS HYDROPHILIC COATING COMPOSITION CAPABLE OF FORMING COATING FILM HAVING EXCELLENT SELF-CLEANING ABILITY AGAINST STAINS ADHERED THEREON, AND SURFACE-TREATED MATERIAL HAVING FORMED THEREON COATING FILM HAVING EXCELLENT SELF-CLEANING ABILITY AGAINST STAINS ADHERED THEREON

摘要

An object of the present invention is to provide an aqueous-based hydrophilic coating composition which is excellent in self-cleaning ability and which can easily remove contamination such as oil contamination which is good in hydrophilicity sustainability of a coating film and permeable. The above object is attained by an inorganic compound (a) obtained by modifying at least one or more of the organoalkoxysilane compound (b) having one or more groups selected from the group consisting of a glycidyl group, a vinyl group and an amino group A), a water-soluble resin (B), and an amorphous silica (C) represented by M ₂ O -SiO ₂ (wherein a mass ratio of M ₂ O / SiO ₂ is 0.05 to 0.3) Based hydrophilic coating composition.
