Abstract
The invention relates to rosin-supported emulsion polymer compositions which are modified with urea-containing monomers and/or urethane-containing monomers reacted with conventional acrylic or styrenic monomers to produce emulsion polymer latices. These emulsion polymer latices can be utilized to formulate printing inks exhibiting superior peel resistances for use in adhesive and extrusion lamination printings.
