Abstract

PURPOSE: To obtain the original plate for the lithographic printing preventing a fault such as slipping-out of the plate by forming the plate of three layers, at least, of a supporting body, a photographic layer and a back-coating layer and thus preventing the slippage.
CONSTITUTION: The basic structure of the aimed original plate is formed by providing the photographic layer, at least, on one surface of the supporting body 1 and the back-coating layer 3 containing 1W50wt% of a slippage-preventing agent on the other. When occasion demands, a pre-coating layer 4 between the supporting body 1 and the photographic layer 2, as well as a water-resisting layer 5 between the pre- coating layer 4 and the photographic layer 2, may further be provided. In addition, as the supporting body, are usable ordinary paper, water-resisting paper, a plastic sheet and the like, while, as the slippage-preventing agent used for the back-coating layer, are usable the grains of glass, alumina, silica and the like, and the average diameter of the grains is preferably 0.5W20μ. Moreover, as the binder for the back- coating layer, are used acrylic resin, styrene resin and the like, while as a water repellent is used polyethylene emulsion and the like.
