PLATE BLANK FOR DIRECT DRAWING TYPE OFFSET PRINTING

摘要

PURPOSE:To enable water resistance and hydrophilic nature to be simultaneously provided and enable favorable fixing properties for a printer ink and a toner used in a PPC copying machine to be obtained, by providing an image-receiving layer comprising as a main constituents an inorganic pigment and a mixed binder consisting of a water-soluble highmolecular weight compound and a synthetic highmolecular weight latex, on a water-resistant base. CONSTITUTION:A coating liquid for forming the image-receiving layer comprising as main constituents an inorganic pigment and a mixed binder consisting of a water-soluble high molecular weight compound and a synthetic high molecular weight latex is applied to the water-resistant base, followed by drying to provide the image-receiving layer. The pigment is preferably a synthetic silica- colloidal silica mixed pigment. The water-soluble high molecular weight compound is preferably polyvinyl alcohol, and the synthetic high molecular weight latex is suitably an acylic emultion. The latex is preferably used in an amount of 5-80pt.wt. per 100pts.wt. of the water-soluble compound.
