ABSTRACT:
A heat sensitive lithographic printing plate precursor is disclosed comprising on a support having a hydrophilic surface or which is provided with a hydrophilic layer, a coating comprising an infrared light absorbing agent and a copolymer which comprises a plurality of recurring units X having a hydrophilic polymeric pendant group and a plurality of recurring units Y having a hydrophobic polymeric pendant group. Said coating is capable of switching from a hydrophilic state into a hydrophobic state after exposure to heat and/or infrared light.
