ELECTROPHOTOGRAPHIC LITHOGRAPHIC PRINTING PLATE

Title:

ELECTROPHOTOGRAPHIC LITHOGRAPHIC PRINTING PLATE

Document Type and Number:

WIPO Patent Application WO/1992/018906

Kind Code:

A1

Abstract:

An electrophotographic lithographic printing plate having a photoconductive layer prepared by the dispersion polymerization of a resin [A] composed of polymer component with specified repeating units and a polar polymer component and having an average molecular weight of 1x10?3� to 2x10?4� and a monomer [C] with a functional group yielding, when decomposed, at least one group selected among thiol, sulfo, amino and ($g(a)) in the presence of a dispersion stabilizing resin soluble in a nonaqueous solvent, said layer further containing dispersed resin particles [L] having silicon- and/or fluorine-containing substituents. This plate has good electrophotographic qualities and water retentivity in virtue of appropriate interactions among zinc oxide, a spectral sensitizer, the resin [A] and the resin particles [L], and gives excellent printed images with a high resistance to abrasion on the press even under severe conditions. Also it works effectively in the scanning exposure process using semiconductor laser beams.
