ABSTRACT:
The invention is water-based printing inks and coatings formulated with stable low viscosity grind bases made from modified rosin grinding resins. These grinding resins are produced via the fusion esterification of fortified rosin with hydroxyacrylic resins and various polyols. Suitable hydroxyacrylic resins are prepared by copolymerizing an hydroxyalkylacrylate or methacrylate with alkyl acrylates, cycloalkyl acrylates, methacrylates, or styrene. These hydroxyacrylic resins can be made to contain a wide range of molecular weights and hydroxyl contents, thereby permitting formulation of a wide variety of soluble grinding resins and printing inks.
