Abstract
Abstract The use of acrylate or methacrylate esters of polyalkylene oxide derivatives of alkyl/aryl phenols as wetting agents and adhesion promoters in ultraviolet curable systems is disclosed. These materials may be added to the ultraviolet system in a quantity between about 5 and 50 weight percent, based on the total weight of the ultraviolet curable composition.
