摘要： The disclosure relates to a metal oxide film formed on a glass substrate by a sol-gel method using a solution of at least one metal alkoxide or acetylacetonate. Water which is in the amount ranging from 50 to 400 mol % of the at least one metal alkoxide or acetylacetonate, an organic solvent and a catalyst are added to the solution, thereby to form a first sol. To afford water repellency to the oxide film, a fluoroalkylsilane in the amount more than 0.30 mol % of and less than 3.0 mol % of the at least one metal alkoxide or acetylacetonate, or an alkylsilane compound in the amount more than 4.0 mol % of and less than 20 mol % of the at least one metal alkoxide or acetylacetonate, is added to the first sol, thereby forming a second sol. The concentration of the at least one metal alkoxide or acetylacetonate in the second sol is adjusted to fall within the range from 0.005 to 3.0 mol %. The second sol is applied to the glass substrate to form a gel film. The gel film is heated at a temperature not lower than 100.degree. C. The obtained oxide film is superior in durability of water repellency.

摘要： The invention relates to a coating liquid for forming a hydrophilic film. This coating liquid comprises a first sol which is a titania sol; and a second sol which is at least one of a silica sol and an alumina sol. This titania sol is prepared by a method comprising the sequential steps of (a) mixing a first solution containing a titanium alkoxide with a diol represented by at least one of the following general formulas (1) and (2), thereby to prepare a second solution containing a titanium complex formed by a reaction of the titanium alkoxide with the diol; and (b) hydrolyzing the titanium complex in the second solution, thereby to prepare the titania sol. The coating liquid is stable or sufficiently long in pot life, and the hydrophilic film has a long time duration in hydrophilicity and a superior abrasion resistance. ##STR1## wherein R.sub.1 is H or C.sub.p H.sub.2p+1 where p is from 1 to 5, R.sub.2 is C.sub.q H.sub.2q+1 where q is from 1 to 5, R.sub.3 is C.sub.r H.sub.2r where r is from 1 to 3, R.sub.4 is H or C.sub.x H.sub.2x+1 where x is from 1 to 5, and R.sub.5 is H or C.sub.y H.sub.2y+1 where y is from 1 to 5.
