Title: Sulfonamido phenol scavenger compounds

Abstract: Photographic elements, film units and processes are described wherein certain ballasted di-2,5-sulfonamidophenols are used to scavenge oxidized electron transfer agents in color image transfer materials. The scavenger compounds can be located in an emulsion layer, a dye image-providing material layer or an interlayer.
