ABSTRACT:
Disclosed is a method for preparation of a printing plate by an electrophotographic process comprising forming a toner image on an electrophotographic light-sensitive element by an electrophotographic process. A peelable transfer layer is provided mainly containing a resin (A) capable of being removed upon a chemical reaction treatment on the toner image. The toner image is transferred together with the transfer layer onto a primary receptor. The toner image together with the transfer layer is then transferred from the primary receptor onto a receiving material having a surface which is capable of providing a hydrophilic surface suitable for lithographic printing at the time of printing. The transfer layer on the receiving material is removed by the chemical reaction treatment.
