Abstract: 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 amine 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.

Abstract: 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.
