  • Patent number: 8524958
    Abstract: A method of preparing an oligomeric or polymeric compound in a liquid solution is disclosed which consists of reacting a Michael donor compound with a Michael acceptor compound in the presence of a first catalyst and a Group IA and/or Group IIA metal ion catalyst.
    Type: Grant
    Filed: June 13, 2008
    Date of Patent: September 3, 2013
    Assignee: Sun Chemical Corporation

  • Patent number: 8119740
    Abstract: The invention describes curable liquid acryloyl group containing compositions, which are produced by reacting monofunctional vinyl compounds and multifunctional acrylic esters with ?-dicarbonyl group containing compounds having two activated hydrogen atoms in its methylene position. These material can be polymerized or crosslinked by free radical polymerization, UV (ultraviolet) or electron-beam radiation. The curable liquid compositions are suitable for producing curable coatings, printing inks, adhesives, or molding compositions.

  • Patent number: 7780744
    Abstract: Compositions, methods, apparatuses, kits, and combinations are described for permanently or temporarily re-designing, decorating, and/or re-coloring a surface. The compositions useful in the present disclosure include a décor product that is formulated to be applied and affixed to a surface. If desired, the décor product may be substantially removed from the surface before being affixed thereto. If a user desires to remove the décor product, the décor product is formulated to be removed by a number of methods including, for example, vacuuming, wet extraction, chemical application, and the like. If the user desires to affix the décor product to the surface in a permanent or semi-permanent manner, the décor product may be affixed to the surface by applying energy thereto in the form of, for example, heat, pressure, emitted waves, an emitted electrical field, a magnetic field, and/or a chemical.
