ABSTRACT:
Photographic elements, film units and processes are described wherein N-alkyl- or N-aryl-benzisoxazolones are used to scavenge oxidized electron transfer agents in negative-working, color image transfer elements. The scavenger precursor compounds can be located in an emulsion layer or in a dye image-providing material layer, and in a ballasted form can be located in an interlayer.
