Zusammenfassung:PROBLEM TO BE SOLVED: To improve ink accepting property, ink release property and white dot defects during storage with time of a lithographic printing plate using a silver complex salt diffusion transfer method and having an aluminum supporting body, to improve thin line image reproducibility and to obtain wide development latitude. SOLUTION: In the lithographic printing plate having a physical developing nuclei layer between a roughened and anodically oxidized aluminum supporting body and a silver halide emulsion layer, the printing plate has an intermediate layer formed mainly of succinated gelatin between the silver halide emulsion layer and the physical developing nuclei layer.
