Abstract

This invention relates to an electrophotographic reproduction process for the preparation of printing plates from electrophotographic reproduction material in which a latent electrostatic image is produced on a layer containing at least one polymerizable organic photoconductor having olefinic double bonds therein, or capable of forming such bonds during heating, the image is made visible by means of a developer which comprises at least one fnely-divided substance which acts as a catalyst for the ionic polymerization of olefins, the reproduction material with the developed image thereon is heated to a temperature between about 50 DEG and 300 DEG C., and the organic photoconductor layer then is removed in a conventional manner from the non-image areas by dissolving it away.
