Abstract: A process for making UV curable pressure sensitive adhesive compositions by derivatizing an acrylic polymer with a derivatizing agent prepared from a hydroxy-functional acrylate monomer and a diisocyanate. The derivatizing agent typically has a ratio of hydroxy-functional acrylate monomer to diisocyanate greater than about 1:1. Also disclosed are UV curable pressure sensitive adhesives made with the derivatizing agent and methods for adhering substrates with pressure sensitive adhesive compositions.
