Abstract:
The present invention provides water-based energy curable compositions that exhibit improved printability, adhesion, opacity, and wash-up properties. The compositions comprise one or more inert water-based polyurethane resins and one or more water-based phosphate esters. Addition of the inert polyurethane resins and phosphate esters improves adhesion of the energy curable compositions to a variety of substrates.
