Abstract (en)
[origin: WO2019072701A1] The invention relates to a digitally imageable, photopolymerizable relief precursor, at least comprising, arranged one atop the other in the specified sequence, (A) a dimensionally stable carrier; (AH) optionally, an adhesion-promoting layer; (B) a relief-forming layer, at least containing a crosslinkable elastomer binding agent, a first ethylenically unsaturated monomer and a photoinitiator; (C) at least one intermediate layer, at least containing a first, non-radically crosslinkable elastic polymer; (D) a laser-ablatable mask layer, at least containing a second, non-radically crosslinkable elastic polymer, a UVA light-absorbing material and an IR light-absorbing material; and optionally (E) a detachable cover layer; characterized in that the layer (C) and, optionally, the layer (D) contain at least a second ethylenically unsaturated monomer.
