  • Curable aqueous dispersions of acrylate-modified polyamide resin
    Patent number: 5109053
    Abstract: Aqueous dispersions of acrylate-modified polyamide resin having unreacted acrylate functionality are provided. These acrylate-modified polyamide dispersions cure upon exposure to either ultraviolet radiation or thermal energy to form cross-linked films useful, for example, as adhesive coatings. In a preferred embodiment, acrylate-modified dispersions are formed by the addition of a polyol ester having a multiplicity of acrylate ester groups to a polyamide resin having a multiplicity of free amino groups under conditions effective to form the Michael addition product thereof.
    Type: Grant
    Filed: June 21, 1990
    Date of Patent: April 28, 1992
    Assignee: Union Camp Corporation
    Inventors: George A. Smith, Daniel T. Rumack, Charles R. Frihart
  • Toluene soluble polyamide resin from polymerized fatty acid and 1,2-diamino cyclohexane
    Patent number: 4816549
    Abstract: Polyamide resins are produced by reacting diamines, polymeric fatty acids, and monoamines. The monoamine component serves as a chain stopper and renders the polyamide resin product soluble in toluene. The resulting resins are especially useful as binder components in printing inks, and are distinguished by their ready solubility in toluene alone.
