摘要： A dye-forming or imaging composition, element and method are disclosed, wherein a cobalt(III) complex containing releasable ligands is converted to cobalt(II) and the ligands by heating in the presence of a first destabilizer compound. The temperature at which the conversion reaction is initiated is unexpectedly lowered by the addition of a second, different destabilizer compound.

摘要： A radiation-sensitive element is disclosed including a radiation-sensitive layer comprised of a cobalt(III)complex and a photoreductant. A process is disclosed in which the photoreductant is converted to a reducing agent by exposure to electromagnetic radiation longer than 300 nanometers. The reducing agent is then reacted with a cobalt(III)complex. Images can be recorded directly within the radiation-sensitive layer or in a separate image-recording element or layer by use of the residual cobalt(III)complex not exposed or one or more of the reaction products produced by exposure. By using the ammonia liberated from ammine ligand containing cobalt(III)complexes on exposure in combination with imagewise and uniform exposures, positive or negative images can be formed in diazo image-recording layers or elements associated with the radiation-sensitive layer.

摘要： An imaging member, such as a negative-working printing plate, can be prepared using a hydrophilic heat-sensitive imaging layer comprised of a hydrophilic heat-sensitive, crosslinked vinyl polymer containing recurring organoonium groups. The imaging member can also include a photothermal conversion material such as carbon black or an infrared radiation absorbing dye. The heat-sensitive polymer has recurring units containing an organoammonium, organophosphonium or organosulfonium group that reacts to provide increased oleophilicity (ink receptivity) in response to heat. Heat is preferably generated by laser irradiation in the IR region of the electromagnetic spectrum. The heat-sensitive polymer is considered “switchable” in response to heat. The imaging member can be used in printing methods without the usual wet processing steps.

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.

摘要： A dye-forming electrothermographic element comprises an electrically activatable recording layer comprising (a) a reducing agent or reducing agent precursor capable of being activated by a Lewis base; (b) a cobalt(III) Lewis base complex; and (c) at least one of (i) a reducible dye-forming compound that has an oxidation state above that of the conjugate dye, (ii) a dye capable of changing its wavelength of absorption by reaction with a Lewis base, and (iii) a dye-forming coupler capable of reacting with the oxidized form of the reducing agent in (a) to form a dye. A negative or positive dye image is formed in such a dye-forming electrothermographic element by applying an electrical potential imagewise to the element of a magnitude and for a time sufficient to produce in the image areas a charge density sufficient to produce a latent image; and, then, heating the element to a temperature and for a time sufficient to form a dye image in the element. The dye-forming electrothermographic element can be a multicolor, multilayer electrothermographic element.
