<p>Photohardenable electrostatic master with improved backtransfer characteristics comprising (1) an electrically conductive substrate, and (2) a layer of photohardenable composition consisting essentially of (a) at least one organic polymeric binder, (b) at least one compound having at least one ethylenically unsaturated group, and (c) a photoinitiator or photoinitiator system, and (d) an acidic additive as defined. A xeroprinting process is described using the master. The master is used in graphic arts, color proofing which duplicates images produced by printing, preparation of printed circuit boards, resists, soldermasks, etc.</p> |
