Patent number: 5506008Abstract: Lacquer films sensitive to ultraviolet (UV) and/or electron beam radiation re applied to substrates as masking layers by a process known as the "spin on process". This invention is a new method of applying a lacquer film sensitive to UV and/or electron beam radiation. A vinyl-containing substance and a linear or cyclic siloxane are vaporized and then deposited onto the substrate to be masked. In the preferred embodiment of the invention, the substances utilized are octamethylcyclotetrasiloxane and trivinylmethylsilane.Type: GrantFiled: July 19, 1994Date of Patent: April 9, 1996Assignee: Fraunhofer-Gesellschaft zur Forderung Der Angewandten Forschung e.V.Inventors: Armin Klumpp, Erwin Hacker

Patent number: 5486578Abstract: The present invention relates to curable silicone coatings containing silicone resins. More particularly the present invention relates to curable silicone coating compositions comprising an olefinic organopolysiloxane, an organohydrogensiloxane, a platinum catalyst, and silicone resins in which the resins are prepared by a continuous method whereby the ratio of reactants is kept constant thus producing less variation in the final silicone resin that is produced. The silicone resins provide beneficial release properties when added to curable silicone coating compositions.Type: GrantFiled: December 20, 1994Date of Patent: January 23, 1996Assignee: Dow Corning CorporationInventors: Leslie E. Carpenter, II, Robert A. Ekeland

Patent number: 5470616Abstract: Disclosed are shaped articles having a coating layer formed on surface region, wherein the surface region is formed of a polymer derived from a multifunctional acrylic monomer and having 0.02 to 0.2 .mu.mol/cm.sup.2 of acidic groups therein, by curing a coating composition consisting essentially of a specific silica polycondensate. The silica polycondensate is obtained by mixing (I) colloidal silica and (II) a specific silicon compound in such a molar ratio that the average number of hydrolyzable groups is within the range of 2.30 to 3.85, and then subjecting them to cohydrolysis and polycondensation. In these shaped articles, the coating layer have excellent properties such as hardness and abrasion resistance, as well as good adhesion.Type: GrantFiled: September 14, 1994Date of Patent: November 28, 1995Assignee: Mitsubishi Rayon Co., Ltd.Inventors: Masamoto Uenishi, Tsukasa Mizobuchi, Masatoshi Takesue, Yukio Kobayashi, Shoichi Nagai

Patent number: 5461691Abstract: The present invention is directed to a beam-curable coating composition for coating glass surfaces, particularly, optical glass fibers. The resultant coatings show slight or no loss of adhesion after exposure to moisture. The coating composition includes ethylenically unsaturated polyurethane, ethylenically unsaturated monomer, photoinitiator and a silane compound. The silane compound is an azidosilane and is added to improve adhesion of the coating agents exposed to moisture. Optionally, aminoalkoxysilanes may also be included.Type: GrantFiled: May 26, 1994Date of Patent: October 24, 1995Assignee: BASF Lacke + Farben AGInventors: Stephan Schunck, Horst Hintze-Bruning, Rainer Blum

Patent number: 5437896Abstract: Method of preparing a composite material comprising a silica network and chains of a polyhydroxy compound which are interwoven therewith and a liquid crystal display device having a top coat of such a composite material.A description is given of a method of preparing a composite material comprising a silica network and, interwoven therewith, chains of, for example, polyhydroxyalkyl acrylate, by first photopolymerizing a tetraalkenyl orthosilicate with UV-light and subsequently converting it into the composite material by subjecting it to a sol-gel treatment. The material obtained is optically transparent. In addition, the material exhibits very little shrinkage so that it can be deposited on a substrate in relatively thick layers. The composite material is very suitable for a top coat 5 on a color-filter layer 3 in a liquid crystal display device because, inter alia, it adheres well to the ITO layer 7.Type: GrantFiled: July 6, 1994Date of Patent: August 1, 1995Assignee: U.S. Philips CorporationInventors: Johan G.
