Abstract
1413744 Electro-photographic process SCOTT PAPER CO 5 Feb 1973 [11 Feb 1972] 5636/73 Heading G2H A method of electro-photography comprises the steps of (a) applying an overall charge to an electro-photographic material comprising a base support having a photo-conductive layer thereon, (b) applying a layer of a dielectric liquid to the charged surface of the photo-conductive layer, (c) placing an original to be copied in contact with the layer of dielectric liquid, (d) imagewise exposing the material for light passing through the original, (e) separating the original from the exposed material and (f) developing the image. Examples of suitable dielectric liquids are given.
