PURPOSE:To provide good sensitivity to the above original plate and to improve the photoresponsiveness thereof by incorporating a specific copolymer into the binder resin of a photoconductive layer. CONSTITUTION:The binder resin of the photoconductive layer contains the copolymer contg. at least one kind of monomer components which contain at least one kind of functional groups forming at least one hydroxyl groups. The hydroxyl group-forming functional groups form the hydroxyl groups by decomposition and the hydroxyl group to be formed from one functional group may be one or >=2. The polymer component contg. the hydroxyl group-forming functional groups is incorporated into the resin preferably at 1 to 99wt.%, more preferably 5 to 95wt.% of the weight of the total polymer if the resin is the copolymer. The printing original plate for electrophotographic process having the good sensitivity and the high response speed is obtd. in this way. |
