Abstract
Ultraviolet curable aqueous emulsion coating compositions are provided in which the discontinuous phase of the emulsion is constituted by liquid droplets of ultraviolet curable polyethylenically unsaturated material (such as an epoxy polyacrylate dissolved in liquid monoacrylate monomer). These liquid droplets are stabilized in the emulsion by means of a polyoxypropylene-polyoxyethylene emulsifier which serves as a cosensitizer, especially when the photosensitizer is a phenyl ketone, such as benzophenone.
