    Abstract: A planographic printing plate precursor includes a support having disposed thereon a recording layer containing a water-insoluble and alkali-soluble resin, a development inhibitor and an infrared absorber and exhibiting enhanced solubility in an aqueous alkali solution through light exposure. The recording layer may have either a mono-layer construction or a multi-layer construction containing a lower layer and an upper layer. In the case of the multi-layer construction, a layer containing the water-insoluble and alkali-soluble resin is used as the lower layer, and a layer containing the water-insoluble and alkali-soluble resin and the development inhibitor and exhibiting enhanced solubility in an aqueous alkali solution through light exposure is used as the upper layer, and at least one of the lower layer and the upper layer contains the infrared absorber.
