Abstract (en)

The present invention provides an electrophotographic printing plate precursor wherein the binder resin contained in the photoconductive layer is formed of a copolymer containing at least one monomeric component component represented by the following formula (I) and at least one monomeric component having an acidic functional group copolymerizable with said first monomeric component, said copolymer having an acidic functional group bonded to one terminal of its main chain and having a weight-average molecular weight lying in the range of 1 x 10<3> to 1 x 10<4>, whereby its response speed and sensitivity to etching can be improved with elimination of fogging problems. <CHEM> wherein R stands for an aliphatic or aryl group.
