A hard coat agent composition comprising an active energy ray-curable compound is applied onto a surface of an article 1 to be hard-coat-treated, thereby forming a hard coat agent composition layer, a surface material layer is formed by film-forming with a surface layer material comprising an active energy ray-curable compound having anti-staining property and/or lubricating property on the surface of the hard coat agent composition layer, and active energy rays are irradiated onto the formed hard coat agent composition layer and surface material layer so as to cure the two layers simultaneously, thereby forming a hard coat layer 2 contacting the surface of the article 1 and an anti-staining surface layer 3 contacting the surface of the hard coat layer 2.Type: GrantFiled: December 20, 2002Date of Patent: November 18, 2008Assignee: TDK CorporationInventors: Naoki Hayashida, Kazushi Tanaka

Patent number: 7285579Abstract: Solventless siloxane epoxy-based coating compositions for use on metals, plastics, wood, and glass are disclosed. The compositions are cationically curable in air by U.V. or by electron beam radiation. The siloxane epoxy coating compositions exhibit excellent film properties after curing, such as good adhesion, flexibility, and appearance. The coating compositions may be clear or may contain fillers, dyes, and pigments. A method for manufacturing a coated metal, plastic, wood, or glass substrate using the compositions is also disclosed, as well as the coated material manufactured by the method.Type: GrantFiled: March 15, 2005Date of Patent: October 23, 2007Assignee: Polyset Company, Inc.Inventor: Ramkrishna Ghoshal

Patent number: 7264669Abstract: A gradient coating is comprised of a basecoat derived from a polysiloxane prepolymer obtained from a mixture of one to three alkoxysilane monomers and at least one diepoxide monomer, and a lubricious reactant. The basecoat is applied to a substrate and dried. The lubricious reactant is then applied and allowed to permeate into the basecoat. The basecoat and lubricious reactant are then co-cured, resulting in a gradient coating composition. In addition to providing enhanced scratch and mar resistance, the gradient coating composition is solvent resistant and provides a durable hydrophobic and oleophobic surface, which makes it useful as a corrosion protectant and as a release agent.Type: GrantFiled: February 3, 2005Date of Patent: September 4, 2007Assignee: Tribofilm Research, Inc.Inventors: Charles Tomasino, Charles K. Chiklis, Vinay G. Sakhrani

Patent number: RE39045Abstract: A method of contacting a substrate having a surface containing hydroxyl groups with a non-aqueous solution containing a material having a chrolosilyl group; washing if desired; coating the substrate with a non-aqueous solvent containing a compound having a fluorocarbon group and a chlorosilane group or a solvent containing a compound containing a fluorocarbon group and an alkoxysilane; and baking the substrate if necessary in order to form a fluorocarbon-based polymer coating film chemically bonded to the substrate surface. The hydroxyl groups on the substrate surface and chlorosilyl groups are reacted to form a thin film having a large number of silanol groups (—SiOH) capable of connecting the polymer coating film to the substrate to form a heat-, weather-, and wear-resistant film on various surfaces.Type: GrantFiled: October 24, 2000Date of Patent: March 28, 2006Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Kazufumi Ogawa, Mamoru Soga
