High Opacity Polymer Composition for Printing Inks |
摘要 |
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. |
