摘要： A presensitized plate for use in making a lithographic printing plate comprises a substrate; a photosensitive layer and a mat layer whose projections have an average diameter of not more than 100 .mu.m, an average height of not more than 10 .mu.m and whose coated amount ranges from 5 to 200 mg/m.sup.2, the photosensitive layer and the mat layer being applied onto the upper surface of the substrate; and a coating layer of an organic polymeric compound having a glass transition point of not less than 20.degree. C. and a thickness ranging from 0.01 to 8.0 .mu.m, the coating layer being applied onto the back face of the substrate. The presensitized plate makes it possible to solve the problem of the formation of scratches and the adhesion of the photosensitive layer to the back face of the PS plate even when a large number of PS plates are transported and/or stored while putting them in piles without sandwiching the PS plate between interleaves. The coated layer applied to the back face of the PS plate is tough and shows good adhesion to the substrate and is not peeled off during handling, development processing and printing operations.

摘要： A method for processing a photosensitive copying material comprises the steps of imagewise exposing to light a photosensitive copying material which comprises in order (i) a first photosensitive organic coating layer whose solubility in a developer varies through irradiation with light rays and (ii) a second organic coating layer containing a water-insoluble and organic solvent-soluble polymeric compound having an film-forming ability and then developing the imagewise exposed copying material, wherein the imagewise exposed material is dipped in the developer and then water-washed to remove the first and second organic coating layers on non-image portions. According to this method, the ability of the developer to process photosensitive copying materials is substantially improved, the amount of the waste liquor can substantially be reduced and a problem of environmental pollution can effectively be solved.
