Process for the preparation of printing forms

In the process for the preparation of printing forms or metallic etchings from electrophotographic or electrographic reproduction materials composed of a support with a photoconductive organic or high-ohmic organic layer thereon, by charging and imagewise exposure, or by imagewise charging, development of the electrostatic image with a finely divided toner, fixing, and removal of the layer in the image-free areas by means of a decoating solution,

• the improvement which ccomprises developing the electrostatic image with a developer which chemically reacts at least superfically with the image areas of the photoconductive organic or high-ohmic organic layer at room temperature, thereby simultaneously effecting development and resistance to the decoating solution,
• or developing the electrostatic image with a developer which chemically reacts with the decoating solution and thereby deactivates it in the image areas.
