Summary:PROBLEM TO BE SOLVED: To provide a photosensitive planographic printing plate excellent in development latitude, that is, both sensitivity and the residual film rate of an unexposed part after alkali development and free of the impairment of processing stability even when many plates are developed with a developing solution. SOLUTION: The photosensitive planographic printing plate has a positive type photosensitive composition layer containing (A) a photothermal converting material, (B) an alkali-soluble resin, (C) a surfactant having an HLB(hydrophile- lipophile balance) of <10 and (D) a surfactant having an HLB of >=10 on the base.
