Abstract
Embodiments of the present invention involve three-layer printing members having a central layer that is non-conductive yet abalatable at commercially realistic fluence levels. In various embodiments, the central layer is polymeric with a dispersion of nonconductive carbon black particles therein at a loading level sufficient to provide at least partial layer ablatability and water compatibility of the resulting ablation debris.
Claims14
A lithographic printing member comprising:
- (a) a first layer presenting a hydrophilic or oleophobic lithographic affinity;
- (b) a second layer for ablating in response to an imaging pulse, the second layer consisting essentially of a polymeric matrix and, dispersed therein, nonconductive carbon black particles at a loading level sufficient to confer at least partial ablatability with formation of water-compatible imaging debris;
- and
- (c) a third layer presenting an oleophilic lithographic affinity, the second layer being disposed between the first and third layers.
