Abstract: A planographic printing plate precursor comprises: a support; and a recording layer disposed on the support, the recording layer comprising a lower layer and an upper layer disposed on the lower layer, wherein the lower layer contains a resin having in a main chain structure a phenol skeleton and a urea bond, the upper layer contains a water-insoluble alkali-soluble resin and an infrared absorber, and the solubility of the upper layer in an aqueous alkali solution is increased by exposure. The planographic printing plate precursor can be produced directly through scanning exposure based on digital signals. It is superior in reproducibility of highly fine images and also superior in printing durability and chemical resistance of small-area image areas such as halftone dots and thin lines.
