Abstract

A photopolymerizable mixture containing one or more ethylenically unsaturated, photopolymerizable or photocrosslinkable compounds and a photopolymerization initiator which comprises a combination of an aromatic carbonyl compound of the type stated in claim 1 and an s-triazine compound containing one or more halogen-substituted methyl groups, photosensitive recording elements which possess a photopolymerizable recording layer consisting of these photopolymerizable mixtures, and a process for the production of lithographic printing plates using these recording elements.
