    摘要： Provided is a planographic printing plate precursor having the advantages of good developability in printers, high sensitivity and a long press life. On a support having a hydrophilic surface with hydrophilic graft polymer chains existing therein, formed is a thermosensitive layer containing a polymer having, in the molecule, a functional group capable of interacting with the hydrophilic graft polymer and a functional group that undergoes hydrophilicity/hydrophobicity conversion through exposure to heat, acid or radiation to fabricate the planographic printing plate precursor.

    摘要： A negative planographic printing plate precursor includes a negative recording layer on a support. The support has a hydrophilic surface with hydrophilic graft polymer chains present therein. The negative recording layer contains a radical generator, a radical-polymerizing compound, and a photo-thermal converting agent. Preferably, the hydrophilic graft polymer chains are directly bonded to the support surface or to an intermediate layer formed on the support surface, or are introduced into a crosslinked polymer film structure.

    摘要： 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.
