Abstract

The disclosed light-sensitive recording material is composed of an electrically conductive support, suitable for the production of printing forms or printed circuits, and a photoconductive layer system containing a photoconductor, a binder, a sensitizing dye and conventional additives. The photoconductive system comprises (A) a single photoconductive layer, or multiple layers, applied to the support and (B) a light-sensitive covering layer which contains at least one photochemically reactive compound. The use of the recording material in a process for the production of printing forms and printed circuits is also disclosed.
