Abstract
An imaging member is composed of a heat-sensitive imaging layer having a heat-sensitive hyperbranched polymer containing heat-sensitive active end groups, and optionally a photothermal conversion material. Upon application of energy that generates heat, such as from IR irradiation, the polymer is rendered either more hydrophobic or hydrophilic depending upon the type of heat-sensitive active end groups present in the polymer. The exposed imaging member can be contacted with a lithographic printing ink and used for printing with or without post-imaging wet processing. This imaging member is particularly useful for direct write imaging using IR lasers or thermal printing heads.
