ABSTRACT:
A photopolymerizable composition for the manufacture of printing plates and relief plates, based on a mixture, containing a photoinitiator, of photopolymerizable olefinically unsaturated monomers and a polymeric binder, contains up to 0.1% by weight of an etherified thioanthraquinone for improving the relief image in the production of relief plates.
The composition advantageously also contains a small amount of an organic tertiary amine or of an aromatic .alpha.-ketocarboxylic acid or its ester and/or of an inhibitor, e.g. the salt of an organic N-nitrosohydroxylamine.
