Patent number: 6979493Abstract: A polyurethane resin having a total concentration of the urethane group and the urea group of not less than 15% by weight is prepared by reacting a diisocyanate component (e.g., an aromatic diisocyanate) with a diol component (e.g., a C2–8alkylene glycol). The repeating unit of the polyurethane resin may contain a constitutive unit of an aromatic or alicyclic compound. The polyurethane resin may be shaped into a film for use as a gas barrier film. The film may be a gas barrier composite film composed of a base film layer and a resin layer at least comprising the polyurethane resin. The present invention provides a polyurethane resin excellent in gas barrier properties against water vapor, oxygen, aromatics, and others, and a film containing the same.Type: GrantFiled: April 10, 2003Date of Patent: December 27, 2005Assignee: Mitsui Takeda Chemical Inc.Inventors: Takashi Uchida, Tsutomu Tawa, Hiroyuki Shiraki

Patent number: 6903158Abstract: The current invention relates to a coating composition comprising a polyisocyanate compound, a hydroxyl-functional film-forming polymer, and a non-volatile branched monoalcohol. An aliphatic branched monoalcohol is preferred. More preferred are long chain non-volatile branched monoalcohols. This results in coating compositions that have improved flow behavior and that produce coatings having improved appearance without an adverse effect on other properties. The invention also relates to a multi-component coating composition. Preferably, the multi-component coating composition is a two-component coating composition comprising a polyisocyanate component and a hydroxyl-functional component, wherein the hydroxyl-functional component, in addition to the hydroxyl-functional film forming polymer also comprises the non-volatile branched monoalcohol.Type: GrantFiled: August 10, 2001Date of Patent: June 7, 2005Assignee: Akzo Nobel N.V.Inventors: Antonius H.G. Van Engelen, Alexander Leo Yahkind, Omar Abu-Shanab, Jason Weaver

Patent number: 6897251Abstract: A clearcoat composition and method reduce the ability of rain to bead on a film of the clearcoat. The clearcoat includes a resin, a cross-linking agent reactive with the resin, and a water-soluble surfactant. Upon exposure of the film to the rain, the surfactant reduces the ability of the rain to bead on the film and certain properties, such as resistance to etch from acid rain, are improved.Type: GrantFiled: November 21, 2002Date of Patent: May 24, 2005Assignee: BASF CorporationInventors: John E.
