摘要： Infrared radiation-sensitive compounds have been found that are represented by Structure DYE as follows: wherein R is a secondary or tertiary amine that contains no heterocyclic group, R1 and R2 are independently carbocyclic aromatic groups, and M+ is a monovalent cation. These compounds have a &lgr;max above 700 nm and are can be used in a number of photosensitive or heat-sensitive imaging materials.

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： A positive-working imaging member is composed of a heat-sensitive surface imageable layer having a heat-sensitive polymer containing heat-activatable sulfoimino, sulfoalkyl, or sulfoamide groups, and a photothermal conversion material. Upon application of thermal energy, such as from IR irradiation, the sulfonate groups decompose rendering exposed areas more hydrophilic. The exposed imaging member can be contacted with a lithographic printing ink and used for printing without post-imaging wet processing. This imaging member is particularly useful for direct write imaging using IR lasers or thermal printing heads.

摘要： An imaging member is composed of a hydrophilic imaging layer having a hydrophilic heat-sensitive polymer containing heat-activatable thiosulfate groups, and optionally a photothermal conversion material. Upon application of energy that generates heat, such as from IR irradiation, the polymer is crosslinked and rendered more hydrophobic. The imaging layer is disposed on an interlayer on a support, which interlayer comprises a Group IVB element (such as titanium, hafnium or zirconium) compound for improved mechanical and imaging properties. 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.

摘要： 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.
