摘要： Disclosed are water repellent glass having an improved durability and an optimum process for producing the same. The water repellent glass includes a glass substrate, and a water repellent film coated integrally on the glass substrate and including ceramics. The ceramics includes SiO.sub.2 at least, and part of nonmetallic atoms of the ceramics are substituted with a fluoroalkyl group. Hence, the water repellent film is cross-linked with the glass substrate mainly by the siloxane bonds. Consequently, the water repellent film is excellent in terms of the adhesion to the glass substrate, it is less likely to be adversely affected by the alkali components of the glass substrate, and it is less likely to come off. As a result, the water repellent glass comes to have an improved durability. This superb water repellent glass can be produced by the optimum production process including the steps of a solution preparing step of preparing a solution, a coating step of coating a paint film on a glass substrate with the solution, and a burning step of burning the paint film. The solution includes first silicone alkoxide expressed by a chemical formula Si(OR).sub.4, second silicone alkoxide, part of whose alkoxyl groups are substituted with a fluoroalkyl group, alcohol, water, and acid or base.
