This protective method includes applying a removable protective coating made of at least one polymer layer, or at least one polyvinyl alcohol layer, to the glass substrates by spraying or rolling the polyvinyl alcohol or a polymer solution of the polymer to be applied in a polar organic solvent, onto the glass substrate, or dipping the substrate into it. Then when the substrate is ready for its end use, the protective coating is removed by washing in water or polar organic solution so that a residue does not remain on it. The glass substrates, protected in this manner have outstanding surface quality and improved hard disk blanks can be economically produced from them.Type: ApplicationFiled: May 5, 2000Publication date: September 26, 2002Inventors: Andreas Weber, Reiner Mauch, Roland Buerkle, Andreas Berndt, Drik Schlatterbeck, Marten Walther

Patent number: 6447897Abstract: Poly-n-isopropylacrylamide surface coatings demonstrate the useful property of being able to switch charateristics depending upon temperature. More specifically, these coatings switch from being hydrophilic at low temperature to hydrophobic at high temperature. Research has been conducted for many years to better characterize and control the properties of temperature sensitive coatings. The present invention provides novel temperature sensitive coatings on articles and novel methods of making temperature sensitive coatings that are disposed on the surfaces of various articles. These novel coatings contain the reaction products of n-isopropylacrylamide and are characterized by their properties such as advancing contact angles. Numerous other characteristics such as coating thickness, surface roughness, and hydrophilic-to-hydrophobic transition temperatures are also described.Type: GrantFiled: May 10, 2000Date of Patent: September 10, 2002Assignee: Battelle Memorial InstituteInventors: Liang Liang, Peter C. Rieke, Kentin L. Alford

Patent number: 6423170Abstract: High clarity optical and safety glass laminate interlayer films and optical laminates are described. The films and their laminates comprise very low density polyethylene and/or its copolymers, preferably polymerized with metallocene catalysts, and modified with additives, such as coupling agents, clarifying or nucleation agents, UV-light absorbers, pigment or color concentrate, and IR-light blockers. The very low density polyethylene is laminated to EVA film for improved bondability in optical laminates.Type: GrantFiled: July 25, 2000Date of Patent: July 23, 2002Assignee: Saint-Gobain Performance Plastics CorporationInventors: Michael Friedman, Glenn T. Visscher

Patent number: 6420036Abstract: The present invention relates to electrochromic ploymeric solid films, manufacturing electrochromic devices using such solid films and processes for making such solid films and devices. The electrochromic polymeric solid films of the present invention exhibit beneficial properties and characteristics, especially when compared to known electrochromic media. The electrochromic polymeric solid films are transformed in situ from a low viscosity electrochromic monomer composition by exposure to electromagnetic radiation, and in so doing minimum shrinkage occurs. The electrochromic polymeric solid films of the present invention also perform will under prolonged coloration, outdoor weathering and all-climate exposure, and provide an inherent safety aspect not known to electrochromic media heretofore.Type: GrantFiled: January 27, 2000Date of Patent: July 16, 2002Assignee: Donnelly CorporationInventors: Desaraju V. Varaprasad, Mingtang Zhao, Craig Allen Dornan, Anoop Agrawal, Pierr-Marc Allemand, Niall R. Lynam

Patent number: 6420020Abstract: An antifogging article includes a substrate and an antifogging film covering the substrate. This antifogging film contains a water-absorbing organic polymer and an inorganic substance and has a water repellent finishing on a surface of the antifogging film. Another antifogging article includes (1) a substrate, (2) a water-absorbing, antifogging film covering the substrate, and (3) a water-permeable, protective film covering the antifogging film. This antifogging film contains (a) a polyvinyl acetal resin having a degree of acetalization of not greater than 10 mol % and (b) a hydrolysate or partial hydrolysate of an alkylsilylisocyanate represented by the general formula R2nSiR14−n where R1 is an alkyl group having a carbon atom number of 1 or 2, R2 is an isocyanate group, and n is 1 or 2. These antifogging articles are superior in antifogging property and abrasion resistance.Type: GrantFiled: November 17, 2000Date of Patent: July 16, 2002Assignee: Central Glass Company LimitedInventors: Seiji Yamazaki, Noboru Murata, Hideki Yamamoto
