Abstract
The planographic printing plate precursor of the present invention comprises a support, and a hydrophilic layer disposed on the support and having a hydrophilic graft chain and a crosslinked structure formed by hydrolyzing or polycondensing an alkoxide of an element selected from Si, Ti, Zr and Al, wherein the hydrophilic layer comprises a photothermal conversion agent (A) and a compound (B) capable of forming a hydrophobic surface area by being heated or irradiated with radiation, and the photothermal conversion compound (A) is not included in the compound (B). This planographic printing plate precursor can be set, without being developed, onto a printer after images are formed, so as to perform printing. In addition, the precursor has remarkably improved printing stain resistance and printing resistance.
