COATING SOLUTION FOR FORMING TRANSPARENT SILICA FILM AND METHOD FOR PRODUCING TRANSPARENT SILICA FILM

摘要

PROBLEM TO BE SOLVED: To provide a coating solution for forming a transparent silica film stable even as the solution and readily forming a relatively thick silica film by coating once without using an organic solvent and to provide a method for producing the transparent silica film.;SOLUTION: The aqueous coating solution comprises at least one kind of silicon compound selected from the group consisting of silicon oxide, silicic acid and silicic acid hydrate having silanol groups, an organic strong base and a water-soluble polymer. The coating solution for forming the transparent silica film is characterized as dissolving the silicon compound in a water-soluble coating solution in the presence of the organic strong base.;COPYRIGHT: (C)2004,JPO
