Abstract
The present invention provides low solvent or substantially solvent-free multi-ethylenically unsaturated acrylate composition imbibed particles of an acid functional group containing acrylic polymer for ultraviolet curing coating applications and methods of making the same wherein the acrylic polymer is formed by polymerizing in organic solvent, then neutralized and combined with a multi-ethylenically unsaturated acrylate composition prior to dispersing the mixture into water and, preferably, removing solvent.
