  • Rosin-fatty acid vinylic polymers as grind resins and grind vehicles comprising same
    Patent number: 6503971
    Abstract: This invention relates to novel rosin-fatty acid vinylic polymer compositions that exhibit characteristics which make them useful as grind resins for preparing grind vehicles for ink and coating formulations. In particular, this invention relates to rosin-fatty acid vinylic grind resin compositions obtained from the addition polymerization reaction of a mixture of rosin and fatty acid and a mixture of (meth)acrylic and vinylic monomers.
    Type: Grant

    Date of Patent: January 7, 2003
    Assignee: Westvaco Corporation
    Inventors: Rajnikant Shah, Stanley C. Adams
  • Rosin-fatty acid vinylic polymers
    Patent number: 6437033
    Abstract: Vinylic polymer compositions having a weight average molecular weight in the range of about 4,000 to about 12,000 are produced by reacting, in an addition polymerization reaction, a fatty acid rosin mixture and a monomer mixture at a temperature in the range of about 135° C. to about 175° C. These compositions exhibit properties that make them useful as support resins for ink and overprint formulations and as additives for formulating various coating compositions.
