    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. By the selection of amine-responsive reducing agent precursors, the amines released by the cobalt(III)complexes cause an amplified image.

    摘要: A radiation detecting element, particularly a photographic element having a radiation detecting composition, in particular a silver halide emulsion. The composition provides the element with a wavelength of peak sensitivity, .lambda.peaksens, and a decreasing sensitivity around .lambda.peaksens. An absorber dye of defined characteristics is chosen, which has the effect of decreasing the change in sensitivity which the element otherwise has without the absorber dye (that is, the absorber dye increases the wavelength range over which the sensitivity is relatively constant). The element is preferably sensitive to infra-red.
