Abstract: A laminated glass for a window, comprising: a first glass sheet layer comprising a first main surface to face an outside of the window and a second main surface facing other layers; a second glass sheet layer comprising a third main surface facing other layers and a fourth main glass surface to face a room side; an IR-reflective coating layer, comprising at least one silver layer, on a whole area of at least one of the second and third main surfaces; a first intermediate polymer film layer between the first and the second glass sheet layers; and a sealant on all the way through an edge portion of the IR-reflective coating layer.

Abstract: Disclosed is an antifogging film-forming material obtained by reacting, in the presence of a quaternary ammonium salt or quaternary phosphonium salt, a copolymer represented by a certain general formula with a multifunctional epoxy compound having a solubility of 40-100 mass % in 25° C. water. The antifogging film-forming material is characterized by having a weight average molecular weight of 100,000-5,000,000. With this material, it becomes possible to obtain an antifogging article excellent in antifogging property, heat resistance, chemical resistance and abrasion resistance.

Abstract: The present invention relates to a glass substrate which is characterized in that it has a primer layer that is formed thereon and includes a hydrolysis product of a hydrolysable silicon compound having an alkylene group and a hydrolysis product of a hydrolysable zirconium compound or hydrolysable titanium compound, and that, in the primer layer, zirconium is in an amount by weight ratio of 0.0002 times to 0.0025 times that of silicon, or titanium is in an amount by weight ratio of 0.0005 times to 0.0045 times that of silicon. Furthermore, the present invention relates to an anti-fogging article having a resin film that exhibits water-absorptive property and/or hydrophilic property and is formed on the primer layer of the glass substrate.

Abstract: The present invention relates to a coating agent for forming an antifogging film on a substrate. This coating agent is formed of a solvent and a mixture containing: (A) an organic isocyanate; (B) a water-absorbing polyol; (C) an acryl polyol; and (D) a surface active agent having an active hydrogen group.
