Abstract
A method for preparation of a printing plate by an electrophotographic process comprising forming a peelable transfer layer capable of being removed upon a chemical reaction treatment on a surface of an electrophotographic light-sensitive element, forming a toner image by an electrophotographic process on the transfer layer, heat-transferring the toner image together with the transfer layer onto a receiving material having a surface capable of providing a hydrophilic surface suitable for lithographic printing at the time of printing, and removing the transfer layer on the receiving material upon the chemical reaction treatment wherein the transfer layer is formed by an electrodeposition coating method using thermoplastic resin grains (AL) each containing a rein (A.sub.1) having a glass transition point of from 10.degree. C. to 140.degree. C. or a softening point of from 35.degree. C. to 180.degree. C. and a resin (A.sub.2) having a glass transition point of not more than 45.degree. C. or a softening point of not more than 60.degree. C. and its glass transition point or softening point is at least 2.degree. C. lower than that of the resin (A.sub.1). The transfer layer according to the present invention has excellent transferability onto a receiving material under transfer conditions of low temperature and high speed to form transferred images of good qualities thereby providing prints of good image qualities.
