The present invention is a windshield for an automobile on which an information acquisition device configured to acquire information from the outside of a vehicle by emitting and/or receiving light can be arranged. The windshield includes: a laminated glass including an information acquisition region that is opposite to the information acquisition device and through which the light passes; and an antifog sheet in which at least a sticky layer, a substrate film, and an antifog layer are layered in this order, the sticky layer being attached to at least a surface on a vehicle interior side of the information acquisition region. The laminated glass includes at least one glass plate in which surface concentrations of tin oxide in two principal surfaces are different, and a surface of the glass plate in which the concentration of tin oxide is higher faces the vehicle interior side.

Windshield and windshield manufacturing method

The coated glass sheet of the present invention includes: a glass sheet; and a coating film provided on at least one principal surface of the glass sheet and having a smooth surface. The coating film includes: isolated closed pores present within the coating film; and a matrix. The coating film is substantially free of open pores open at the surface of the coating film. For the coated glass sheet of the present invention, a transmittance gain is 2.5% or more, the transmittance gain being calculated by subtracting an average transmittance of the glass sheet as determined by applying light having wavelengths of 380 to 1100 nm to the glass sheet in the absence of the coating film on the surface of the glass sheet from an average transmittance of the coated glass sheet as determined by applying light having the wavelengths to the coated glass sheet from a side on which the coating film lies.

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.

The coated glass sheet of the present invention includes: a glass sheet; and a coating film provided on at least one principal surface of the glass sheet. The coating film includes a dense layer and a porous layer. The dense layer is positioned between the porous layer and the glass sheet.

Coated glass sheet and method for producing same

The present invention provides a glass article including a photocatalyst filmcontaining silicon oxide particlesand titanium oxide particles, and a glass sheet. Assuming that the photocatalyst filmhas a film thickness T, 80% or more of the titanium oxide particles are localized in a region between a surface of the glass sheetand a position spaced from the surface by 0.6 T toward a surface of the photocatalyst filmin a thickness direction of the photocatalyst film. The glass article has an increased transmittance provided by enhancing the reflection-reducing function of the photocatalyst filmwhile maintaining the film strength and photocatalytic function of the photocatalyst film

Glass article provided with photocatalyst film, process for producing glass article, and coating liquid

A low-reflection coating of the present invention is a porous film including: fine silica particles being solid and spherical and having an average particle diameter of 80 to 150 nm; and a binder containing silica as a main component, the fine silica particles being bound together by the binder. The binder further contains an aluminum compound. The low-reflection coating contains, as components, 55 to 70 mass % of the fine silica particles, 25 to 40 mass % of the silica of the binder, and 2 to 7 mass % of the aluminum compound in terms of AlO. The low-reflection coating has a thickness of 80 to 800 nm. The low-reflection coating yields a transmittance gain of 2.5% or more when provided on the substrate. The transmittance gain represents an increase in average transmittance of the substrate provided with the low-reflection coating relative to the substrate not provided with the low-reflection coating, the average transmittance being measured in the wavelength range of 380 to 850 nm.

Low-reflection coating, low-reflection coated substrate, and photoelectric conversion device

A cover glass of the present invention for photoelectric conversion devices includes a glass sheet having surface asperities and a reflection-reducing film formed over the surface asperities of the glass sheet. The surface asperities of the glass sheet have an average spacing Sm of 0.3 mm or more and 2.5 mm or less and an arithmetic average roughness Ra of 0.3 &#x3bc;m to 5 &#x3bc;m. The reflection-reducing film includes fine silica particles having an average particle diameter of 50 to 200 nm and a binder for the fine silica particles, and the fine silica particles are uniformly arranged in a single layer on peak portions of the surface asperities in such a manner that a filling fraction F is 35 to 65%. A transmittance gain is 2.37% or more, the transmittance gain being obtained by subtracting an average transmittance of the glass sheet as measured when light having wavelengths ranging from 380 to 1100 nm are incident on a face of the glass sheet that has the surface asperities, from an average transmittance of the cover glass as measured when light having the wavelengths are incident on a reflection-reducing film side of the cover glass. Thus, a cover glass for photoelectric conversion devices that exhibits a high transmittance gain is provided.

The present invention provides a glass article including a photocatalyst filmcontaining silicon oxide particlesand titanium oxide particles, and a glass sheet. Assuming that the photocatalyst filmhas a film thickness T, 80% or more of the titanium oxide particles are localized in a region between a surface of the glass sheetand a position spaced from the surface by 0.6 T toward a surface of the photocatalyst filmin a thickness direction of the photocatalyst film. The glass article has an increased transmittance provided by enhancing the reflection-reducing function of the photocatalyst filmwhile maintaining the film strength and photocatalytic function of the photocatalyst film.

Glass article provided with photocatalyst film

Provided is a glass article that improves the film strength of a photocatalyst film while maintaining the photocatalytic function and the reflection suppressing function of the photocatalyst film. The photocatalyst film on the glass sheet is formed to contain, in mass %, 50 to 82% of silicon oxide particles, 8 to 40% of titanium oxide particles, and 7 to 20% of a binder component composed of silicon oxide. The average particle diameter of the silicon oxide particles is set to at least 5 times the average particle diameter of the titanium oxide particles. The photocatalyst film is formed to have a structure such that some of the silicon oxide particles in the film serve as protruding silicon oxide particles that are not in contact with the glass sheet and that have their top portions protruding from the surrounding titanium oxide particles and being exposed on the surface of the film, while some of the titanium oxide particles are interposed between the glass sheet and the protruding silicon oxide particles.
