ABSTRACT:
Yellowing of a processed photographic element is inhibited by incorporating a scavenger comound capable of reacting with magenta coupler, e.g. an epoxy compound, in a layer adjacent a layer containing the magenta coupler. In a preferred embodiment, the magenta coupler containing layer is sandwiched between layers containing the scavenger compound. Prior to processing at least one of these layers contains a solubilizing agent for the scavenger compound. In preferred embodiments, the processing solution used to process the photographic element containing an external solubilizing agent for the scavenger compound, preferably benzyl alcohol.
