Abstract

PURPOSE:To obtain a fresh printed product by forming as the resin of photoconductive layer copolymer of 10-20mol% of acrylic acid ester and/or methacrylic acid ester and monobasic or bibasic acid, thereby forming only the non-image part in a hydrophilic state. CONSTITUTION:In a wet type electrophotographic lithographic printing original plate formed with a precoating layer made of waterproof resin such as urethane resin or the like and zinc oxide or resin acid series photoconductive layer on a conductive support made of paper of plastic film, acrylic resin having suitable hydrophobic property in which 10-20mol% of acid component of the resin of the photoconductive layer is copolymerized is employed. Monobasic acid and bibasic acid to be copolymerized may include acrylic acid, malieic acid or fumaric acid. Since such copolymeric acrylic resin has suitable hydrophilic property, only non-image part is formed to be hydrophilic, though etched. Accordingly, the printed material becomes distinct.
