Abstract
In a process for reducing halations during the imagewise irradiation of a reproduction layer exposed through a planar image original, at least one lubricant either is contained in the layer or is interposed between the layer and the image original. Suitable lubricants include organic polysiloxanes, hydrocarbon polymers, polyaryl esters, and alkanoic acids or alkenoic acids having at least 9 carbon atoms. Excluded are lubricants comprising copolymers of dimethyl dichlorosilane, ethylene oxide and propylene oxide, provided they are located in the reproduction layer.
