RELIEF PRECURSOR HAVING LOW CUPPING AND FLUTING

摘要

A digitally imageable, photopolymerizable relief precursor at least comprising, arranged one above another in the order stated,(A) a dimensionally stable carrier;(AH) optionally, an adhesion-promoting layer;(B) a relief-forming layer, at least comprising a crosslinkable elastomeric binder, a first ethylenically unsaturated monomer, and a photoinitiator;(C) at least one interlayer, at least comprising a first, non-radically crosslinkable elastic polymer;(D) a laser-ablatable mask layer, at least comprising a second, non-radically crosslinkable elastic polymer, a UVA light-absorbing material, and an IR light-absorbing material; and optionally(E) a removable cover layer;characterized in that the layer (C) and optionally the layer (D) comprise at least one second ethylenically unsaturated monomer.
