摘要： A thermographic element comprising in a non-aqueous binder medium a silver salt oxidizing agent in reactive association with a compound comprising a plurality of redox color releasing moieties such that oxidation of each redox color releasing moiety causes release from said compound of a thermally diffusible dye.The compounds many of which are new incorporate two or more developer moieties into a single molecule to minimize the diffusibility of the compound. Following oxidation, either directly by the silver salt or by means of a cross-oxidizing agent, each oxidized developer moiety releases a thermally diffusible dye. The compounds are of sufficient size and molecular weight to slow or prevent diffusion in imaging systems and yet possess several active developer moieties per molecule which is advantageous over known ballasted dye releasers which comprise bulky molecules with only a single developer moiety.

摘要： A photothermographic element comprising a reflective base having coated thereon one or more layers constituting a photothermographic imaging medium in which a bleachable antihalation medium is coated over said photothermographic imaging medium, the components of the antihalation medium being in non-reactive association with components in the photothermographic imaging medium. The topcoat antihalation layer allows a wide latitude in the selection of dye bleach systems and binders and surprisingly is at least as effective as the use of antihalation underlayers.
