Abstract
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.
