Abstract: A glass plate includes a first surface and a second surface that is opposite to the first surface. A concave portion is formed on the first surface toward the second surface side with reference to the first surface. A convex portion is formed on the first surface toward a side opposite to the second surface with reference to the first surface.

Abstract: There is provided a vehicle windshield which can decrease chances of a fogging to occur by having an antifogging property, and under a situation that a fogging occurs, it is able to allow a driver to easily and surely recognize an occurrence state of the fogging in its initial state without adversely affecting visibility. The vehicle windshield has a window glass, a strip-shaped black ceramic layer, and a water absorbing antifogging film, wherein the water absorbing antifogging film has a thin-film area located outside a visual field area where a visual field of a driver is ensured in the vehicle windshield and inside an area where the black ceramic layer is formed, the thin-film area having a maximum film thickness in a range of 30% to 70% of a minimum film thickness in the visual field area and having a size recognizable by the driver when a fogging occurs.

Abstract: An anti-fogging article having a substrate and an anti-fogging film on at least part of the surface of the substrate, wherein the anti-fogging film comprises a resin underlayer and a water-absorptive resin layer laminated in order on the substrate surface, the water-absorptive resin layer is composed mainly of a first cured epoxy resin obtained by reacting a water-absorptive resin layer-forming composition containing a first polyepoxide component consisting of a low molecular weight polyepoxide having molecular weight of from 200 to 800 and a high molecular weight polyepoxide having molecular weight of from 900 to 2,000 combined in mass ratio of from 30:70 to 70:30, and a first curing agent, and the resin underlayer is composed mainly of a second cured epoxy resin obtained by reacting a resin underlayer-forming composition containing a second polyepoxide component and a second curing agent, and has water absorption property lower than the water-absorptive resin layer.

Abstract: An antifogging glass is provided which has not only an excellent antifogging property but also an excellent appearance and provides an excellent visual effect to an observer. An antifogging glass for a vehicle window, comprising a glass sheet for a vehicle window and an antifogging film disposed on an interior side of the glass sheet, the glass sheet having a dark concealment region disposed in a band-shape on a peripheral edge portion thereof, and the antifogging film having an edge present in a position closer to a central portion of the glass sheet than an edge of the glass sheet and in the dark concealment region.
