Abstract
An electrophotographic plate-making material comprising a paper support and a photoconductive layer is described. This paper support is prepared by providing a polyolefin resin layer on both surfaces of a paper substrate by molten extrusion lamination, and is characterized in that the volume electric resistance is not more than 10.sup.10 .OMEGA. and the polyolefin resin layer contains electrically conductive carbon black having a loss on drying, as determined under the conditions of 110.degree. C. and 2 hours, of not more than 1.0%. Using this plate-making material, there can be produced a lithographic printing plate having good dimensional stability and long press life.
