ABSTRACT:
Undesirable particle growth of particles comprising a hydrazide oxidized developer in a photographic dispersion can be significantly reduced when the hydrazide scavenger is in the form of a dispersion of crystalline solid particles dispersed in an aqueous medium. The dispersion is 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.
