PLATE MATERIAL FOR LITHOGRAPHIC PRINTING AND METHOD FOR PRODUCING LITHOGRAPHIC PRINTING PLATE

摘要

Disclosed is a plate material for lithographic printing, wherein an image-receiving layer is formed on a supporting body. This plate material for lithographic printing is characterized in that the image-receiving layer contains an amorphous silica, a colloidal silica and a hydrophilic adhesive. Also disclosed is a method for producing a lithographic printing plate, which is characterized in that an image-receiving layer containing an amorphous silica, a colloidal silica and an adhesive is formed on a supporting body, and an oleophilic image is formed on the image-receiving layer by electrophotography.
