Claim:
1. A laminate comprising a) a photopolymerizable relief-forming layer comprising an elastomeric binder, ethylenically unsaturated monomers, a photoinitiator, and optionally further additives; b) an elastomeric substrate layer which is optionally photopolymerizable comprising an elastomeric binder, optionally ethylenically unsaturated monomers, a photoinitiator, and optionally further additives; wherein said photopolymerizable relief-forming layer a) has a hardness of 30 to 70° Shore A and said elastomeric substrate layer b) has a hardness of from 75° Shore A to 70° Shore D in the photopolymerized state, and wherein said elastomeric substrate layer b) has a hardness of at least 5° Shore A greater than that of said photopolymerizable relief-forming layer a), and wherein the photopolymerizable relief-forming layer a) is present on the elastomeric substrate layer b).
