elektrophotographische printing plate as the starting material for a printing plate, and method for their production lithographische.

摘要

An electrophotographic lithographic printing plate precursor capable of giving a good image free from pinholes is provided which comprises an electrically conductive base (2) coated, on one side thereof, with an undercoated layer (3) and a photoconductive layer (1) containing zinc oxide as a predominant component in order and on the opposite side thereof, with a back layer (4), said undercoated layer (3) having a surface resistivity of 1x108 to 1x1014 OMEGA and said back layer (4) having a surface resistivity of at most 1x1010 OMEGA .
