摘要
The present invention provides a process for forming a hydrophilic inorganic coated film on a surface of a base material, the process comprising the steps of: (1) preparing an inorganic coating composition which contains, as a major component, a silicone resin obtained by hydrolyzing and condensation-polymerizing only the tetra-functional alkoxysilane represented by the formula: Si(OR)4 [wherein R represents an alkyl group having carbon atoms up to and including 7 or an aryl group], and has a total solid content of not more than 5% by weight; (2) applying the inorganic coating composition to a surface of the base material to form a coated layer; and (3) drying and curing the coated layer to form a cured coated film having a thickness of 0.01 to 0.5µm. The hydrophilic inorganic coated film formed by the process of the present invention is highly hydrophilic just after the film is formed, even in the case that it is not irradiated with ultraviolet rays.
