    摘要: 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: 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.

    摘要: 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.
