ABSTRACT:
Disclosed is a method for making a printing plate which comprises forming a toner image by electrophotography on a master plate which comprises a base and an organic photo-conductive compound-containing layer, the binder for said organic photo-conductive compound being a half ester resin of a styrene-maleic anhydride copolymer and then subjecting non-image areas other than the toner image areas to an etching treatment with a solution mainly composed of an alkali and/or an alcohol. Thus obtained printing plate is excellent in printing endurance and, besides, can be rapidly etched.
