ABSTRACT:
Photohardenable electrostatic master comprising an electrically conductive substrate, e.g., aluminized polyethylene terephthalate, bearing a layer of a photopolymer comprising an organic polymeric binder, compound having at least one ethylenically unsaturated group, photoinitiator and at least one organic electron acceptor or donor compound, e.g., the acceptor and donor having an oxidation potential of less than +2.5 eV and reduction potential larger than -3.0 eV, respectively. The photohardenable electrostatic master is used for electrostatic proofing, etc.
