Abstract

PURPOSE: To provide a master free of stains on the texture by providing a blend of an inorganic pigment and a denatured polyvinyl alcohol on a support.
CONSTITUTION: An image-receiving layer consisting of an inorganic pigment such as a clay, calcium carbonate and zinc oxide and a specified denatured polyvinyl alcohol is provided on a water-resistant support consisting of wood free paper increased in wet strength by a melamine-formaldehyde resin or a urea-formaldehyde resin or other similar material. For producing an original plate for direct picturing type planography, an aqueous solution containing a denatured polyvinyl alcohol and an inorganic pigment is coated on the water-resistant support and is dried at 100W150°C to form an image-receiving layer of about 5W20μm in thickness. Accordingly, since the denatured polyvinyl alcohol is made to be water-resistant and hydrophilic by heat or by a cross-linking agent when the image-receiving layer is formed, a master free of texture stains and excellent in durability can be produced.
