摘要：
An imaging member, such as a negative-working printing plate or on-press cylinder, has an imaging layer comprised of a thermally sensitive ionomer (charged polymer) and a photothermal conversion material that is a bis(aminoaryl)polymethine dye that is soluble in water or a water-miscible organic solvent, and that has a &lgr;max greater than 700 nm as measured in water or the water-miscible organic solvent.
