Abstract

The present invention provides a top coat layer for a printing plate precursor. The top coat layer includes polycyanoacrylate particles, but is substantially free of photothermal conversion material. The topcoat layer may be applied onto a thermally sensitive layer containing polycyanoacrylate particles and a photothermal conversion material. The top coat layer may reduce ablation during radiation exposure without adversely affecting printing plate performance.
