Abstract
This invention relates to an electrophotographic process for the production of a printing form which comprises electrostatically charging a supported photoconductive and photopolymerizable layer, exposing the charged layer to light under a master, developing the resulting latent image with an electroscopic material, again exposing the layer to light, and removing the developed image areas from the support.
