ABSTRACT:
Yellowing of a processed photographic element is inhibited by incorporating a scavenger compound capable of reacting with magenta coupler, e.g. an epoxy compound, in a layer adjacent a layer containing the magenta coupler. 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 contains an external solubilizing agent for the scavenger compound, preferably benzyl alcohol.
