Photopolymerizable mixtures of at least 40% by weight of an elastomeric block copolymer of a styrene and a diene, at least 1% by weight of a photopolymerizable monomer and 0.01 to 10% by weight of at least one photopolymerization initiator contain, as the elastomeric block copolymer, one of the structure ABC, in which A a thermoplastic, non-elastomeric polymer block with a glass transition temperature above + 25 ° C from at least one styrene compound, B an elastomeric polymer block with a glass transition temperature below -20 ° C from at least one conjugated diene hydrocarbon and C a polymer block different from B with a glass transition temperature between -30 ° C and + 15 ° C from at least one conjugated diene hydrocarbon and optionally a styrene compound. The photopolymerizable mixtures are particularly suitable for producing light-curable elements with a photopolymerizable layer on a layer support. |
