    Abstract: The present invention relates to a negative-working radiation imageable lithographic printing plate precursor, preferably having only two polymeric layers on a support. The first (bottom) layer is composed of oleophilic polymers and a photothermal converter which converts radiation to heat. The second polymeric layer (top) is composed of crosslinked hydrophilic polymers which absorb aqueous fountain solution and repel ink. The oleophilic polymers in the first layer contain functional groups are interlayer chemically bonded to the hydrophilic polymer in the second layer to provide interlayer adhesive bonding between the two layers. The plate is imagewise exposed to radiation, such as with an IR laser, resulting in non-ablative adhesion-weakening between the two layers so that the plate can be developed by fountain solution and/or ink on press whereby the top layer in the exposed area is removed on the press to reveal the ink-receptive image area. The top layer in the unexposed area remains as the non-image area.
