ABSTRACT:
The present invention relates to a planographic printing plate precursor comprising a substrate comprising a hydrophilic surface having disposed thereon a heat-sensitive layer containing a thermoplastic particulate polymer having functional groups capable of interacting with the hydrophilic surface. Preferably, hydrophilic graft polymer chains are present on the hydrophilic surface of the substrate. The present invention further relates to a planographic printing plate precursor comprising a substrate comprising a hydrophilic surface having disposed thereon a heat-sensitive layer comprising microcapsules comprising a compound having functional groups capable of interacting with the hydrophilic surface. In addition, the present invention relates to methods of printing with the planographic printing plate precursors.
