摘要:
A method for preparation of a printing plate by an electrophotographic process comprising forming a peelable transfer layer mainly containing a resin (A) capable of being removed upon a chemical reaction treatment on the surface of an electrophotographic light-sensitive element, forming a toner image on the transfer layer by an electrophotographic process, heat-transferring the toner image together with the transfer layer onto a receiving material a surface of which is 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 prior to or simultaneously with the formation of transfer layer a compound (S) which contains a fluorine atom and/or silicon atom is applied to the surface of electrophotographic light-sensitive element to improve releasability of the surface of electrophotographic light-sensitive element.The method continuously provides printing plates excellent in image qualities in a stable manner and is suitable for a scanning exposure system using a laser beam.An apparatus suitable for performing the present method is also disclosed.
