PURPOSE:To provide the photosensitive planographic printing plate which is improved in a side etch preventive effect and electrophotographic characteristics (sensitivity, gamma and dark attenuation), is prevented from surface staining at the time of printing, is shortened in plate making time (by shortening of full-surface exposing time) and is prevented from staining by sticking of laminated paper, etc., at the time of depositing and drying in the process of production of the photosensitive planographic printing plate to a photosensitive layer. CONSTITUTION:This photosensitive planographic printing plate has the photosensitive layer contg. a photoconductive material, quinonediazide compd. and binder resin on a conductive base. This plate contains a copolymer contg. hydroxyphenyl methacrylamide or hydroxyphenyl acrylamide as a monomer component. |
