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： A coupler containing in the coupling position a carbamoyloxy group ##STR1## upon oxidative coupling, releases a carbamic acid fragment that, in turn, is capable of thermally releasing ammonia or an amine. Such a carbamoyloxy substituted coupler and carbamic acid fragment are useful in imaging such as in photothermography and thermography. Ammonia or an amine released from the carbamic acid fragment enables imaging in imaging materials that are responsive to ammonia or an amine. The carbamoyloxy substituted coupler also generally is a dye-forming coupler that reacts with the oxidized form of a color developing agent to form a dye. An image is produced in an exposed photothermographic material comprising the carbamoyloxy substituted coupler by thermal development. An image is produced in a thermographic material comprising the carbamoyloxy substituted coupler and a color developing agent by imagewise heating the thermographic material.

摘要： A redox release compound that is capable upon oxidation of releasing a silver ion complexing heterocyclic thio moiety enables reduction of the concentration of silver required in a photographic silver halide material comprising a combination of (i) photographic silver halide capable of forming a surface latent image, and (ii) a photographic silver halide capable of forming an internal latent image. The silver halide capable of forming an internal latent image preferably has lower photosensitivity than the silver halide capable of forming a surface latent image. The redox release compound preferably comprises a silver ion complexing 1,2,4-triazolium-3-thio moiety. An image is developed in such an exposed photographic silver halide element by means of a surface type silver halide developer.

Such an imaging material can be a photographic silver halide material. The imaging material can be a photothermographic material for producing a dye image comprising, in reactive association, (a) photographic silver halide, (b) a dye-forming coupler, and (c) an oxidation-reduction image forming combination comprising (1) an organic silver salt oxidizing agent, and (2) an organic reducing agent for the organic silver salt oxidizing agent, wherein the reducing agent is a ureidoaniline which is capable in its oxidized form of reacting with the dye-forming coupler to form a dye. A thermographic material comprises the same combination of components without the need for photographic silver halide. A silver image and dye image are produced in such an exposed photothermographic material by heating the material until the silver image and dye image are produced. An image in a thermographic material is produced by imagewise heating the material. Ureidoaniline silver halide developing agents are also useful in processing compositions for photographic silver halide materials.
