Abstract

Abstract A photopolymerizable mixture is described which contains the following: a binding agent which is soluble or at least capable of swelling in aqueous-alkaline solutions, a photoinitiator or a photoinitiator system and at least one ethylenically unsaturated monomer, whereby at least one monomer contains an aromatic hydroxyl-, mercapto-, sulfonamide- or a mono-N-substituted sulfonamide group, or combinations thereof.
