ABSTRACT:
Sulfilimine compounds of formula I ##STR1## in which R.sup.3 is the residue of a diffusible photographically active compound can be split reductively to release the residue together with a group --SO.sub.2 --NH.sub.2. When R.sup.3 represents the radical of a dye or dye precursor the sulfilimines are useful as color providing compounds in dye diffusion transfer processes.
