Electrophotographic lithographic printing plate precursor

摘要

A lithographic printing plate precursor excellent in oil-desensitivity, whereby an original is faithfully reproduced without occurrence of overall or spotted stains as an offset master is provided, which comprises an electrically conductive support and at least one photoconductive layer, provided thereon, containing photoconductive zinc oxide and a binder resin, in which said photoconductive layer contains hydrophilic resin grains having an average grain diameter of same as or smaller than the maximum grain diameter of said photoconductive zinc oxide grains, and said binder resin contains at least one of Resin A having a weight average molecular weight of 1x103 to 2x104 and Resin B having a weight average molecular weight of at least 3x104.
