Abstract

PURPOSE: To expand the preparing condition and latitude of prescription for an intermediate layer and to satisfy both water-resisting and hydrophilic properties, by providing a specific resin between a water-resisting support and a picture-accepting layer.
CONSTITUTION: An intermediate layer of which chief ingredient is polyamide epichlorohydrin resin is provided between a water-resisting support and a picture- accepting layer. The polyamide epichlorohydrin resin used is a water-soluble resin, and is essentially hydrophilic and water-resisting irrespective of the drying condition of the intermediate layer. The polyamide epichlorohydrin resin can be used alone, or together with another water-soluble resin or white pigment and, if necessary, with an insolubilizing agent, a bridging agent, or other additives. A conventional picture-accepting layer can be used. The method of processing an original plate is also quite the same as a conventional method. By the method mentioned above, an original plate for lithography superior in the printing characteristics and satisfying both hydrophilic and water-resisting properties can be obtained.
