摘要： An image-forming element is disclosed comprised of a support and a coating thereon containing a cobalt(III)complex and a compound containing a conjugated .pi. bonding system capable of forming at least a bidentate chelate with cobalt(III). The coating is predominantly free of anions which will form conjugate acids by deprotonation of a cobalt(II)complex containing the chelating compound. In one preferred form the image-forming element is radiation-sensitive. In this form the image-forming element can contain a photoactivator capable of initiating reduction of the cobalt(III)complex. An imaging process is disclosed in which the coating is exposed to actinic radiation to produce an image. Images can be recorded directly within the image-forming coating or in a separate image-recording element or layer by use of the residual cobalt(III)complex or by use of 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 image-forming coating.

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.
