The invention relates to the use of a coating comprising at least one fatty-acid modified resin as an anti-fingerprint coating on a least one face of a glass sheet. In particular, the invention allows to provide an anti-fingerprint solution to be used for a glass sheet, which does not significantly affect the surface properties and the aesthetics of the coated glass compared to the naked glass. Moreover, the invention allows to provide an anti-fingerprint solution to be used for a glass sheet, which is sustainable in time and/or wearing of the surface.

Disclosed is a method for preventing a photocatalyst from decreasing in hydrophilicity due to contamination by components seeping from a sealing material for anchoring a construction material, exterior material, glass structure, or other article on which a photocatalyst layer is formed. In said method, a transparent sealing-material-component seepage-prevention layer, which contains a modified epoxy resin comprising polymerizable unsaturated monomers graft-polymerized onto or copolymerized with an epoxy resin, is formed on the surface of the sealing material. Said polymerizable unsaturated monomers include a carboxyl-group-containing monomer, and a modified epoxy resin obtained by a carboxyl-group/epoxy-group reaction after graft polymerization or copolymerization is more favorable.

A glass article comprising a glass substrate and a coating on a surface of the glass substrate is disclosed. The coating comprises a glass frit and a binder comprising an interpenetrating polymer network. The interpenetrating polymer network comprises a crosslinked polyol resin, a second crosslinked resin, and a third resin. A method of forming the glass article containing the coating is also disclosed.

Disclosed is a process for producing a film-coated substrate having a relatively flat distribution of film thickness such that the film thickness is suppressed from s gradually increasing toward a downstream side of flow of a coating liquid even when a coating film is formed on a plate-shaped substrate by a flow coating method in which the substrate is held in raised attitude. The film-coated substrate according to the present invention is employed in particular as an openable/closable window glass of an automotive door, and is suitable for one where the substrate includes an uncoated region where no coating film is formed, wherein the uncoated region is configured to be received in a receiving part of an upper frame of the door.

Provided are a vehicle windshield equipped with a transparent film at a visual field area, where a negative effect on a driving visibility due to a boundary line between a forming area and a non-forming area of the transparent film is improved, and a vehicle component having the vehicle windshield. The vehicle windshield includes: a window plate; and a transparent film provided at a surface on a vehicle-interior side of the window plate, wherein the vehicle windshield includes a first area where the transparent film is not provided and a second area where the transparent film is provided, at a central area when viewed from a front side, and a boundary between the first area and the second area has no perspective distortion and is constituted by a boundary line having line width visually recognized by scattering of irradiated light of 10 m to 200 m.

There are provided an antifogging article and automobile glass that not only satisfy a good antifogging property and abrasion resistance but also have a good appearance. An antifogging article includes: a transparent base; and an antifogging layer which is provided on the transparent base and which made of an epoxy resin cured material containing a silicon atom and an aluminum atom, wherein, in the antifogging layer, an antifogging time (T.sub.35) in a 35 C. steam test as measured by a predetermined method is eighty seconds or more, a variation T in haze after a Taber abrasion test stipulated in Japan Industrial Standard (JIS) R3212 is 4.0% or less, and a variation YI in a yellowness index stipulated in JIS K7373 after the antifogging layer is kept at 100 C. for 500 hours is 3 or less.
