ABSTRACT:
A method for the preparation of electrostatic masters, and product prepared thereby, said masters having improved water and pick resistance for lithographic printing. The method comprises applying a barrier coat formulation to a substrate wherein the formulation contains an aqueous dispersion of a copolymer of at least about 60% ethylenically unsaturated polymerizable monomer having non-polar functionality and about 3 to about 40% of a polymerizable olefinically unsaturated monomer having polar functionality.
