<P>PROBLEM TO BE SOLVED: To provide a photosensitive lithographic printing plate material which has excellent resistance to wear, prevents print contamination to be caused by scratches and fingerprints on the surface of the hydrophilic layer, and is improved in the adaptability of a cleaner liquid, with respect to the water-developable photosensitive lithographic printing plate material in which a hydrophilic layer and a photopolymerizable photosensitive layer are layered in this order on a plastic film substrate. <P>SOLUTION: The photosensitive lithographic printing plate material includes a hydrophilic layer and a photopolymerizable photosensitive layer containing a water-soluble polymer, successively formed on a plastic film substrate, wherein the hydrophilic layer contains silicone-based organic fine particles and water glass. <P>COPYRIGHT: (C)2010,JPO&INPIT |
