A windshield according to an aspect of the present invention is a windshield for an automobile on which an information acquisition device capable of acquiring information from the outside of a vehicle by emitting and/or receiving light can be arranged. The windshield includes; a glass plate including an information acquisition region that is opposite to the information acquisition device and through which the light passes; and an antifog laminate that includes a heat blocking layer and an antifog layer with antifog properties layered on one surface of the heat blocking layer, and that is layered on a surface on a vehicle interior side of the information acquisition region while the other surface of the heat blocking layer faces the surface on the vehicle interior side of the information acquisition region.

Windshield and windshield manufacturing method

An aspect of the present invention is directed to a method for producing a glass sheet with a coating, produced by applying a functional liquid for providing a function to the glass sheet, to at least one face of the glass sheet, including a first step of supplying the functional liquid to an ejection portion having a nozzle that ejects the functional liquid toward the glass sheet, and a second step of applying the functional liquid to the glass sheet while moving the glass sheet relative to the ejection portion in a fixed state such that the functional liquid ejected from the nozzle is applied to a predetermined region on the at least one face of the glass sheet, wherein a tube member that transports the functional liquid is connected to the ejection portion, and, in the first step, the functional liquid is supplied by the tube member to the ejection portion.

For obtaining a substrate on the surface of which a water repellent film is firmly bonded through an undercoating film, and which shows a low critical inclination angle, superior durability, and high density, a water repellent and/or oil repellent film layer is formed by using a liquid for undercoating treatment. The liquid for undercoating treatment is obtained by dissolving and reacting a material having chlorosilyl radicle radicle in molecular form therein and is dissolved into an alcohol group solvent, so that a surface roughness (Ra) of less than 0.5 nm is obtained, thereby achieving high durability and a low critical inclination angle.

Substrate having a treatment surface

Coating liquid prepared by dissolving an acid and a silicon alkoxide into alcohol, containing at least one of either a silicon alkoxide or a hydrolyzate thereof (including a partial hydrolyzate) in an amount of 0.010 to 3% by weight (in terms of silica), an acid in terms of 0.0010 to 1.0 normality, and water in terms of 0 to 10% by weight is coated on a substrate to produce an article coated with a silica-based film. By this method for producing a silica-based film coated article, an excellent silica-based film coated article can be obtained without requiring baking and pretreatment. Furthermore, a functional film coated article excellent in durability can be produced in a short period of time and safely by using the abovementioned silica-based film as a primer film and applying thereon an organosilane having a hydrolyzable group and a functional group having a specific function or a hydrolyzate thereof.

This invention provides a water repellant glass plate for vehicles or buildings, which shows a long-term durability. The water repellant glass plate includes a primer layer on a glass substrate, consisting essentially of silicon oxide in which oxygen atoms are partially substituted by hydroxyl groups, at a thickness between 10 nm and 100 nm, and a second layer on the first layer consisting of an organic silicon compound including a fluoroalkyl group at a thickness between about 0.2 nm and about 40 nm.

A sheet of ultraviolet-cutoff glass includes a primer layer, an ultraviolet-cutoff layer, and a water-repellent layer which are successively deposited on a glass sheet. The water-repellent layer is formed of a vitreous water repellent. Since the water-repellent layer doubles as an overcoat layer, it makes it unnecessary to form a overcoat layer in a separate overcoating process.
