A planographic printing plate precursor, including: a substrate; anphotosensitive layer containing an IR absorber, a polymerization initiator,na polymerizable compound and a binder polymer; and a protective layerncontaining a UV absorber, disposed in this order. The photosensitivenlayer exhibits reduction in solubility in an alkaline developing solutionnupon being exposed to light having a wavelength of 750 nm to 1400 nm. |
