Abstract

The invention describes a developing solvent for layers which are crosslinkable by photopolymerization and contain a binder based on an elastomeric polymer, a photopolymerizable monomer compatible therewith and a photoinitiator. The developing solvent comprises a phenol ether of the general formula I ##STR1## wherein R.sup.1 denotes (C.sub.1 -C.sub.6)n-alkyl or iso-alkyl, cycloalkyl or (C.sub.6 -C.sub.12)-aryl and PA0 R.sup.2 denotes hydrogen, (C.sub.1 -C.sub.6)n-alkyl or iso-alkyl or --OR.sup.1. Compared with solvents of the prior art, the developing solvent of the present invention is non-toxic, can quickly be removed from the layer and has a high capacity for layer components.
