The coating is transparent, and comprises a hydroxyl group containing polymer, an aluminum containing crosslinker, and a surface active agent containing hydroxyl and/or siloxane groups. Additionally, the coatings possess a T.sub.fog of greater than about 30 minutes and a haze of less than about 5%, and can advantageously be used to provide to glass or plastic substrates an anti-fogging surface.Type: GrantFiled: May 1, 1996Date of Patent: September 8, 1998Assignee: Arkwright, IncorporatedInventors: Jian Cheng Song, Sen Yang, Kang Sun

Patent number: 5804319Abstract: The invention pertains to a separation device which is to be temporarily inserted between two sheet products, in particular between two plates of glass, and which has differentiated adhesion with these two sheet products. The separation device is essentially made of a thermofusible material which has an ability to absorb shocks and an ability to obtain for one of its two sides, a controlled and desirable adhesion with the sheets to be separated.Type: GrantFiled: June 24, 1996Date of Patent: September 8, 1998Assignees: Saint-Gobain Vitrage, Norton S.A.

Patent number: 5800904Abstract: A composite surface covering includes a substrate and an inorganic wear layer. The composite surface covering retains its performance characteristics after mechanical embossing. Preferably, the inorganic wear layer of the surface covering is deposited on the substrate by a reduced pressure environment vapor deposition technique. Preferably, the inorganic wear layer is aluminum oxide. The preferred substrate is a plastic material.Type: GrantFiled: October 29, 1993Date of Patent: September 1, 1998Inventors: Robert A. Hallman, Robert D. Hensel, Eugene M. Kirchner, Jeffrey S. Ross, Jerome D. Wisnosky

Patent number: 5763062Abstract: The present inventions teaches an optically transparent film or sheet which is greater than or equal to 0.5 mm in thickness and includes an extrudable ionomer resin which comprises a carboxylic acid polymer and which is essentially free of amines. The ionomer resin film can be used alone or in a lamination with polycarbonate or glass. In certain embodiments, it is preferable to partially or fully neutralize the acid polymer with a metal cation.Type: GrantFiled: November 8, 1996Date of Patent: June 9, 1998Assignee: Artistic Glass Products CompanyInventors: W. Novis Smith, Nelson Bolton

Patent number: 5759698Abstract: Laminated glass has sheets of plate glass with a bonding layer intervening therebetween for integration. The bonding layer is formed of a resin composition comprising (A) a terpolymer of ethylene, vinyl acetate, and an acrylate and/or methacrylate monomer, (B) a terpolymer of ethylene, vinyl acetate, and maleic acid and/or maleic anhydride, (C) a terpolymer of ethylene, an acrylate and/or methacrylate monomer, and maleic acid and/or maleic anhydride or (D) an ionomer resin in the form of an ethylene-methacrylic acid copolymer with a metal ion binding molecules thereof as a thermosetting resin, an organic peroxide, and a silane coupling agent. The resin composition is thermoset between the glass sheets.Type: GrantFiled: May 16, 1996Date of Patent: June 2, 1998Assignee: Bridgestone CorporationInventors: Itsuo Tanuma, Yasuhiro Morimura, Hidefumi Kotsubo

Patent number: 5725956Abstract: A method and material is disclosed for protecting glass surfaces in a stack of glass sheets by applying an interleaving material comprised of a high molecular weight polymer having a number average molecular weight of at least 200,000 to one or both major surfaces of the glass sheets. The glass sheets are then stacked in face-to-face relation for shipment or storage.Type: GrantFiled: September 18, 1995Date of Patent: March 10, 1998Assignee: Libbey-Owens-Ford Co.Inventors: Richard J. McCurdy, Kenneth J. Heater, Alice B. Parsons, J. David Robbins

Patent number: 5709951Abstract: A composite deposited film including (A) a polymeric film substrate; (B) a deposit of an inorganic material formed on at least one side of the polymeric film substrate (A); and (C) a water-resistant film laminated on the deposit (B) and formed from a mixture containing a polycarboxylic acid or a partially neutralized product thereof and a saccharide in a weight ratio of 95:5 to 20:80 is provided. A production process of a composite deposited film, which includes the steps of forming a deposit (B) of an inorganic material on at least one side of a polymeric film substrate (A); casting a solution of a mixture containing a polycarboxylic acid or a partially neutralized product thereof and a saccharide in a weight ratio of 95:5 to 20:80 on the deposit (B); drying the mixture to form a film; and then subjecting the resultant dry film to a heat treatment at a temperature not lower than 100.degree. C. (373 K), thereby forming a water-resistant film (C) on the deposit (B), is also provided.Type: GrantFiled: July 13, 1995Date of Patent: January 20, 1998Assignee: Kureha Kagaku Kogyo K.K.Inventors: Tomoaki Sato, Hiroyuki Oba, Hideaki Tanaka, Tomohisa Hasegawa
