Abstract
A planographic printing plate precursor comprising a support and a cross-linking hydrophilic layer disposed thereon, which cross-linking hydrophilic layer has a cross-linking structure and includes a hydrophilic high molecular compound having a hydrophilic graft chain. The planographic printing plate precursor is characterized by the cross-linking hydrophilic layer being produced by reacting a hydrophilic high molecular compound having, on the backbone polymer thereof, a group which is able to react with a cross-linking agent, with the cross-linking agent. In the present invention, an image forming layer may be provided on the cross-linking hydrophilic layer. The cross-linked hydrophilic layer may include a compound which is able to form a hydrophobic surface region of the cross-linking hydrophilic layer when exposed to heat or radiation.
