  • High Opacity Polymer Composition for Printing Inks
    Publication number: 20110283908
    Abstract: High-opacity polyurethane resins are produced by polymerization of polyisocyanates with polymeric polyols and subsequent chain extension with polyamines. The resins provide high-opacity inks when formulated with white pigments, which maintain good extrusion and adhesive lamination bonding strength properties. The inks are useful in flexographic and/or gravure printing processes, particularly as back-up for laminated packaging.

  • POLYURETHANE RESINS FOR LAMINATING INKS
    Publication number: 20110027543
    Abstract: A polyurethane resin which is particularly suitable for use in printing inks for laminating packaging applications is described. The polyurethane resin maintains its lamination bond strength before and after the laminate printed with the ink containing the polyurethane resin is subjected to sterilization conditions. Laminates which maintain a printed image and their structural integrity after sterilization are also described.
