Preparation of photoconductive film using radiation curable resin

摘要

An improvement in the method of preparing a coating or layer of reprographic material upon a substrate which includes the conventional steps of coating the substrate surface with a layer of resinous binder curable upon exposure to radiant energy including electron beam and ultraviolet radiation, the binder layer containing reprographic solids. The resinous binder is applied as a fluid and is irradiated until a coherent and adherent layer is formed. The method includes the steps of forceably applying and tautly maintaining a sheet of a smooth flexible film against the surface of the curable resinous binder while directing a beam of radiant energy through the sheet and onto the binder while the layer of flexible film is held thereagainst. The exposure to radiant energy is continued until the resinous binder is substantially completely cured, whereupon the sheet of flexible film is removed from the surface of the binder. The reprographic solids preferably consist of cadmium sulfide, cadmium selenide, or alloys thereof.
