Abstract
This invention relates to an improvement in the process for the manufacture of printing forms and printed circuits by coating an electrically conductive support with an organic photoconductor layer and by charging, exposing, and developing the electrostatic image by means of a finely particulate toner, fixing and dissolving the layer away from the non-image areas by means of a decoating medium and, if appropriate, etching of the bared support surface, the improvement which comprises, for the purpose of coating, transferring the organic photoconductor layer on a temporary support to the electrically conductive support with the aid of heat and pressure.
