摘要： An imaging member, such as a negative-working printing plate or on-press cylinder, can be prepared using a hydrophilic imaging layer comprised of a heat-sensitive hydrophilic polymer that comprises recurring units comprising quaternary ammonium carboxylate groups. The imaging member can also include an infrared radiation sensitive material to provide added sensitivity to heat that can be supplied by laser irradiation in the IR region. The heat-sensitive polymer is considered “switchable” in response to heat, and provides a lithographic image without wet processing.

摘要： Thermally developable imaging materials have an outermost protective layer that is composed of one or more hydrophilic film-forming components. The predominant film-forming component is a positively-charged latex polymer that has cationic groups. The charged latex polymer is present as latex particles that have prepared in the presence of a non-ionic or cationic stabilizer in an amount of at least 0.5% (by weight) that has an HLB value of 7 to 20. The nonionic or cationic stabilizer becomes associated with the latex polymer particles. Both thermographic and photothermographic materials can be prepared with such protective layers.

摘要： Various imaging members including lithographic imaging members (such as printing plates) have an aqueous-based imaging layer applied to a support. Directly over the imaging layer is a protective layer that is applied as a non-aqueous inverse emulsion comprising highly hydrophilic, water-swellable microgel particles dispersed in a water-immiscible organic solvent. This protective layer provides physical durability but it is still readily removed during or after imaging with water or fountain solutions.

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 dye having multiple sulfo groups. 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.
