Glow polymerisate layers can be generated on a substrate, starting from hydrocarbons and/or fluorocarbons, by means of a high-frequency, low-pressure glow discharge. Glow polymerisates completely saturated with hydrogen or fluorine are obtained when the glow discharge is carried out in the microwave range between 0.5 and 1.000 GHz and if the amplitude E.sub.0 of the effective field strength in the vicinity of the substrate no greater than 850 V/cm.

An electrophotographic recording material is applied on a plate-shaped or drum-shaped substrate in a layer structure of superposed layers which comprises a photoconductive layer and at least the uppermost layer is fashioned of amorphous, hydrogen-containing carbon. The amorphous, hydrogen-containing carbon layer is deposited from a radio frequency excited low-pressure plasma with gaseous hydrocarbon as a reaction gas and in which a self-bias DC voltage is superimposed on the radio frequency field. The a-c:H material obtained in this manner is semiconducting and has photoconductive properties so that it can be employed for the photoconductive layer of the electrophotographic recording material.
