Abstract
A process for the production of a colored image by an electrophotographic route by electrostatic charging, imagewise exposure to light and toning of a photoconductor material with a colorless transparent toner which includes a colorless polymeric binder and a colorless polymeric charge control agent, and transfer of the toner image to a colored layer which is soluble in a solvent and is on a layer carrier, fixing of the toner image and removal of the areas of the colored layer not covered by the toner image by washing out with a solvent. The process utilizes the high photosensitivity of electrophotographic materials, without the possibility of color falsification due to colored toners. The procedure is simpler compared with known electrophotographic processes, since the same toner can be employed in all steps and does not have to be washed off.
