    • 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 0.5 &mgr;m. 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.
    • 本发明提供了在基材表面形成亲水性无机涂膜的方法,该方法包括以下步骤:(1)制备一种无机涂料组合物,其中以无机涂料组合物为主要成分, 并且仅使由式(Si)(OR)4表示的四官能烷氧基硅烷进行缩聚:[其中,R表示碳原子数为7以上的烷基或芳基],总固体成分不多 超过5%重量; (2)将无机涂料组合物涂布在基材的表面上以形成涂层; 和(3)干燥和固化涂层以形成厚度为0.01至0.5μm的固化涂膜。 通过本发明的方法形成的亲水性无机涂膜即使在没有用紫外线照射的情况下,在形成膜之后即具有高亲水性。
