PROBLEM TO BE SOLVED: To provide a lithographic printing original plate of a plastic film support capable of being simply platemade, platemade by directly mounting in a printer and having small scumming and imparting flexibility to the original plate. SOLUTION: The lithographic printing original plate comprises at least a hard intermediate layer and a hydrophilic image recording layer containing a hydrophobic precursor at a surface side from the intermediate layer on the plastic film support. Particularly, the lithographic printing original plate comprises inorganic fine particles in the intermediate layer and/or a photothermal conversion agent in at least one of the image recording layer and its adjacent layer or the hydrophobic precursor. |
