A method of processing a silver bromoiodide photographic element comprising contacting the photographic element with a color developer for less than 120 seconds; wherein the photographic element comprises a support and more than one dye forming unit, and wherein the dye forming unit closest to the support contains an electron transfer agent releasing compound represented by the formula: CAR-(L)n-ETA wherein: CAR is a carrier moiety which is capable of releasing -(L)n-ETA on reaction with oxidized developing agent; L is a divalent linking group, n is 0, 1, or 2; and ETA is a releasable 1-aryl-3-pyrazolidinone electron transfer agent having a calculated log partition coefficient (c log P) greater than or equal to 2.40 bonded to L or CAR through either the nitrogen atom in the 2-position or the oxygen attached to the 3-position of the pyrazolidinone ring.
摘要:
A color photothermographic element comprising at least three light-sensitive units which have their individual sensitivities in different wavelength regions, each of the units comprising at least one light-sensitive silver-halide emulsion, binder, and dye-providing coupler, and a blocked developer in the presence of a thermal solvent represented by the following structure: wherein the groups are as defined in the specification to promote the thermal development of the photothermographic element.
摘要:
This invention relates to a photothermographic color element containing a mixture of blocked developers in the same emulsion layer, which blocked developers having different onset temperatures. Such a mixture has been found to allow for lower film processing temperatures and/or shorter times of development with respect to the blocked developer having a higher onset temperature. Conversely, improved discrimination can be obtained with respect to the blocked developer having the lower onset temperature.

This invention relates to packaged photographic film that is capable of being alternately processed, according to individual consumer choice, by either (1) a traditional wet-chemistry process with a developer solution followed by desilvering in one or more subsequent solutions to obtain a color negative film, or (2) a dry thermal process without the use of aqueous solutions in which a blocked developing agent located within the photographic element is thermally activated or unblocked, optionally followed by electronic scanning of the developed film without desilvering. This invention enables a single film stock to be developed in both a conventional deep tank process and in a dry thermal process.
