Invention Patent: B "THE PROCESS FOR THE PRODUCTION OF ARTICLE FILLED WITH REPELLECTABLE WATER COVER, ARTICLE REVIEWED BY THE REPELLING WATER REPELLER REPELLER, AND LIQUID COMPOSITION FOR REPELLECTING WATER" D . process for the production of a product coated with a water repellent film comprising the application on a base substrate of a coating liquid containing a silicon alkoxide, a silicon-like compound containing a fluoralkyl group and an acid dissolved in a solvent and drying;the process for the production of a product coated with a water repellent film being characterised by the fact that the aforementioned coating liquid contains: 0,01 -2%by weight (converted into sil ica) of such silicon alkoxide or hydrolysed thereof, 0001 -0, 15%by weight (converted into silica) of the aforementioned silane-type compound containing a fluoralkyl group, 0003 -3 normal of that acid, and 0-20% by water weight. By the process, a water repellent product with good waterdrop bearing properties, high scratch resistance and high weathering resistance is provided with excellent productivity.
