A glass window has a multiple glass structure in which a plurality of glass plates face each other, and a film is formed on the glass plate surface that is exposed to a cold environment when the glass window is closed. The film comprises a urethane resin prepared by a polymerization using at least a polyoxyalkylene-series polyol having an average molecular weight of 400-5000 and a hydrophobic polyol. There is used as the hydrophobic polyol an acrylic polyol having an average molecular weight of 500-5000 or a polyester polyol having an average molecular weight of 500-5000 and a hydroxy value of 10-200 mg KOH/g. Thereby, the film absorbs water that is in contact with the film when the glass window is open, and the film releases the water absorbed in the film when the opened door glass is closed, thereby having a condition that the film can absorb water.

The invention relates to a multilayered water-repellent film formed on a glass substrate by the sol-gel process. The film has a first metal oxide layer which is formed on the glass substrate by the sol-gel process and a second water-repellent layer formed on the first layer. As a first method for providing the film with superior durability of water repellency, mechanical strength and chemical resistance, the first layer is prepared by using a mixture of three specific sols which are respectively prepared from metal alkoxides or metal acetylacetonates. As a second method for providing the film with the above advantages, the second layer is prepared by using a coating mixture comprising a fluoroalkylsilane, tin oxide particles doped with antimony oxide, a silicon compound, water and an organic solvent. As a third method for providing the film with the above advantages, the second layer is prepared by using another coating mixture comprising a fluoroalkylsilane, tin oxide particles doped with antimony oxide, a silicon compound, water, an organic solvent and an acid.
