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.
通过添加一个疏水、照相惰性化合物来制备稳定的照相分散体,该化合物的logP.sub.(calc)大约大于9,并且不会使分散相固化或凝胶,所述照相分散体包括一个水性介质和一个分散的液态有机相,所述液态有机相包括一个照相有用化合物,该化合物(i)可溶于有机溶剂,(ii)在水中基本不溶,且(iii)在没有添加照相惰性化合物的情况下,在所述分散体中维持时,其粒子大小至少增长了其初始粒子大小的10%。
