Electrically photosensitive materials comprising electrically photosensitive colorant particles dispersed in a liquefiable, electrically insulating carrier containing a binder polymer and electropolymerizable bisphenol-acrylate monomers or mixtures of such monomers are disclosed. The disclosed materials are employed in photoelectrophoretic processes wherein the colorant particles are caused to migrate by the action of light and an electric field, while the material is electrohardened by the electric field.
