Abstract
Undesirable dye stain in a photographic element containing a disulfonamidophenol oxidized developer scavenger can be significantly reduced when the disulfonamidophenol scavenger is in the form of a crystalline solid particle dispersion prepared by milling crystalline solid particles of the scavenger in an aqueous medium in the presence of a dispersing agent and in the substantial absence of an organic solvent.
