ABSTRACT:
An electrostatic master having improved water, cockle and pick resistance for lithographic printing, and method for making the same, comprising a base, a barrier coat applied to said base, and a photoconductive layer containing a photoconductive material and binder applied to said barrier coat. The barrier coat preferably comprises a copolymer of at least 60% ethylenically unsaturated polymerizable monomer having non-polar functionality and about 3 to about 40% of a polymerizable olefinically unsaturated monomer having polar functionality. The barrier coat preferably contains about 2.5 to about 50% plastic particles based on the weight of the barrier coat. The barrier coat achieves improved water resistance at low coat weights, and thus can be applied without substantial change in conductivity.
