    摘要： An imaging member, such as a negative-working printing plate or on-press cylinder, can be prepared with a hydrophilic imaging layer comprised of a heat-sensitive hydrophilic polymer having ionic moieties and an infrared radiation sensitive oxonol dye that has a &lgr;max of greater than 700 nm. The heat-sensitive polymer and IR dye can be formulated in water or water-miscible solvents to provide highly thermal sensitive imaging compositions. In the imaging member, the polymer reacts to provide increased hydrophobicity in areas exposed to energy that provides or generates heat. For example, heat can be supplied by laser irradiation in the IR region of the electromagnetic spectrum. The heat-sensitive polymer is considered “switchable” in response to heat, and provides a lithographic image without wet processing.

    摘要： This invention relates to a latex composition comprising water as a continuous phase and, as the dispersed phase, hydrophobic polymer particles having associated therewith an infrared polymethine dye having covalently bonded thereto a phenylenediamine moiety. It further relates to a process for associating dye with polymer particles in a latex composition comprising the steps of: (1) forming a dye solution by dissolving a polymethine dye having covalently bonded thereto a phenylenediamine moiety in a water miscible or immiscible organic solvent; (2) forming a latex by dispersing hydrophobic polymer particles in an aqueous continuous phase; (3) blending the latex with the dye solution; and (4) loading of the polymer particles by removing the organic solvent, thereby forming a latex having the polymethine dye associated therewith.
