摘要：
A stabilized photographic dispersion is prepared by adding a hydrophobic, photographically inert compound which has a logP.sub.(calc) greater than about 9 and does not solidify or gel the dispersed phase to a photographic dispersion comprising an aqueous medium and a dispersed liquid organic phase comprising a photographically useful compound which is (i) soluble in organic solvents, (ii) substantially insoluble in water, and (iii) subject to particle growth of at least 10% of its initial particle size when maintained in said dispersion in the absence of the added photographically inert compound.
