Abstract
An electroghraphic lithograph printing plate material having an enhanced spectral sensitivity to semiconductor laser rays, comprises a electroconductive water-resistant support and electrophotographic layer formed on the support and comprising a photoconductive zinc oxide, a binder resin and a sensitizing dye material comprising (a) 30 to 99% by weight of a low adsorption sensitizing dye for which the zinc oxide exhibits a low adsorption rate of less than 90% and (b) 1 to 70% by weight of a high adsorption sensitizing dye for which the zinc oxide exhibits a high adsorption rate for 90% or more, the adsorption rate being measured by spectrophotometry.
