Abstract

A photopolymerisable relief precursor includes a dimensionally stable carrier, and a photopolymerisable relief-forming layer at least containing a crosslinkable elastomeric binder, an ethylenically unsaturated monomer, a migration-capable, surface-active additive, a photoinitiator activatable with UVA light and a photoinitiator activatable with UVC light. A method for producing a relief structure.
