Patent number: 6864295Abstract: Disclosed is a gas-generating, pressure-sensitive adhesive composition comprising a pressure-sensitive, ultraviolet irradiation-curable adhesive (A) containing a photoinitiator, wherein the adhesive (A) transmits therethrough an ultraviolet radiation, and a gas generator compound (B) which generates a gas upon irradiation thereof with an ultraviolet radiation, wherein the gas generator compound (B) is operably combined with the pressure-sensitive, ultraviolet irradiation-curable adhesive (A), so that, in operation, when the gas-generating, pressure-sensitive adhesive composition which is adhered to an adherend is irradiated with an ultraviolet radiation, the gas generator compound (B) generates a gas and the gas effuses at an interface between the gas-generating, pressure-sensitive adhesive composition and the adherend to thereby facilitate release of the adherend from the gas-generating, pressure-sensitive adhesive composition.Type: GrantFiled: July 23, 2002Date of Patent: March 8, 2005Assignee: Asahi Kasei Chemicals CorporationInventor: Yoshiaki Mitarai

Patent number: 6825243Abstract: Provided are an active energy ray-curable urethane (meth)acrylate and an active energy ray-curable composition for paints and coating agents having abrasion resistance and lubricity, and uses thereof. The curable urethane (meth)acrylate has a long chain alkyl group having 13 to 25 carbon atoms and an active energy ray-curable functional group and is modified with polycaprolactone. The urethane (meth)acrylate is obtainable by reacting an organic isocyanate having three or more isocyanate groups in one molecule, a long chain alkyl alcohol, and a polycaprolactone-modified hydroxyethyl (meth)acrylate. On the other hand, the active energy ray-curable composition contains the urethane (meth)acrylate.Type: GrantFiled: August 28, 2002Date of Patent: November 30, 2004Assignee: Natoco Co., Ltd.Inventors: Tomihisa Ohno, Masahiro Hara, Shigekazu Teranishi, Susumu Kawakami

Patent number: 6825245Abstract: In accordance with the present invention, there are provided novel thermosetting resin compositions which do not require solvent to provide a system having suitable viscosity for convenient handling. Invention compositions have the benefit of undergoing rapid cure. The resulting thermosets are stable to elevated temperatures, are highly flexible, have low moisture uptake and are consequently useful in a variety of applications, e.g., in adhesive applications since they display good adhesion to both the substrate and the device attached thereto.Type: GrantFiled: August 1, 2002Date of Patent: November 30, 2004Assignee: Henkel CorporationInventors: Stephen M. Dershem, Dennis B. Patterson, Jose A. Osuna, Jr.
