    摘要: A light-sensitive silver-halide color photothermographic element comprises a typically magenta dye-forming pyrazolone coupler in the cyan record by rendering the hue of the resultant dye a cyan hue. The use of certain para-phenylenediamine developers, for example, containing a substituent group in both the 2- and 6-positions (ortho, ortho') relative to the coupling nitrogen, along with selected magenta dye-forming couplers, when oxidized, yield cyan dyes with certain couplers, resulting in the superior non-hue characteristics of magenta couplers in the cyan layer. By means of the present invention, light sensitive color photothermographic elements can form image dye records of consistent density forming ability and consistent stability in all three color records. Also disclosed is a method of processing such a color photographic element.
