ABSTRACT:
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.
