PROCESS FOR THE PRODUCTION OF A LIGHT-SENSITIVE COPYING MATERIAL WITH A SUPPORT HAVING A COPPER-CONTAINING SUPPORT SURFACE

摘要

A procedure to make a reproductive material with a negative working copy layer based on a non-volatile or only hardly volatile photosensitive mass, and with a copper-containing layer carrier, generating the copy layer by applying a solution of the mass on the layer carrier and drying the applied solution, characterized in that, before or at the same time as the solution containing the photosensitive mass, a sulfurous organic compound is applied to the layer carrier, either before or at the same time minus one mercapto group, or else it is tetramethyldiuram disulfide, in the form of a solution, drying the applied solution.
