Abstract
PURPOSE: To obtain the captioned original plate whose quality is less scattered, in which on a water-resistant support is arranged an image receiving layer containing as major constituents an inorganic pigment and a specified binding agent, so that the hydrophilic and the water-resistant property of the image receiving layer are stabilized.
CONSTITUTION: As a binding agent is used a mixture including a polyvinyl alcohol having carboxyl groups, a carboxymethylcellulose and a polyamide epichlorohydrin resin. The image receiving layer containing as major constituents an inorganic pigment and the binding agent is arranged on a water-resistant support to obtain the lithographic original plate. The total amount of the three resins mentioned above in the binding agent in the combined binding agents should be preferably over 5% by weight. The amount of the inorganic pigment is suitable 40W90% by weight in the total image receiving layer.
