LITHOGRAPHIC PRINTING PLATE

摘要

PROBLEM TO BE SOLVED: To provide a lithographic printing plate which enables inkjet direct platemaking and achieves more excellent printing durability, contamination resistance and an ink desorption property.SOLUTION: A lithographic printing plate includes an image receiving layer A containing mainly inorganic particulates on a water-resistant support, and an image receiving layer B containing either mainly cationic colloidal silica, or mainly colloidal silica and a collaterally-cationic compound on a side distant from the support farther than the image receiving layer A. An application quantity of a solid content of the inorganic particulates contained in the image receiving layer A is 1.0-8.3 g/m.
