ABSTRACT:
Ultraviolet curable aqueous coating solutions are provided in which an hydroxy functional ethylenically unsaturated material, such as hydroxy ethyl acrylate or a polyether or polyester thereof, is dissolved in water with the aid of an amine photoinitiator and a photosensitizer is incorporated in the composition, preferably by reacting the hydroxy functionality in the ethylenically unsaturated material with a tetracarboxylic acid dianhydride including a proportion of benzophenone tetracarboxylic dianhydride which provides the needed ultraviolet photosensitizer.
