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.
A color photothermographic imaging element comprising a pyrazolone coupler in reactive association with a developer precursor that liberates a developing agent, the oxidized form of which forms a cyan colored dye with the pyrazolone coupler in at least one imaging layer of the imaging element, wherein the coupler is selected such that it would have been capable of forming a magenta dye with an oxidized form of the conventional developer 4-(N-ethyl-N-2-hydroxyethyl)-2-methylphenylenediamine.
A method of processing an imagewise exposed photothermographic element comprising thermally developing the imagewise exposed element to form an image and then scanning the element to form a first electronic image representation of the developed image in the element, wherein at least one image recording layer in the element comprises a cyan dye that is the reaction product of a pyrazolone coupler and a phenylene diamine developer or phenylene diamine developer precursor that liberates a developing agent, wherein said coupler is selected such that it would have been capable of forming a magenta dye with an oxidized form of the conventional developer 4-(N-ethyl-N-2-hydroxyethyl)-2-methylphenyenlnediamine.
