Patent ID: 7338756

Claim:
A process for making a direct dispersion of a photographically useful material comprising: mixing (i) an aqueous phase and (ii) a liquid organic phase under conditions of shear or turbulence in the substantial absence of auxiliary solvent to form a direct dispersion of the organic phase dispersed in the aqueous phase; wherein the liquid organic phase comprises one or more photographically useful materials and one or more organic solvents having a boiling point of at least 150° C., a molecular weight less than or equal to 300, and a solvatochromic parameter β value greater than or equal to 0.50, and wherein the weight ratio of the sum of the solvents having a boiling point of at least 150° C., a molecular weight less than or equal to 300, and a solvatochromic parameter β value greater than or equal to 0.50 to the photographically useful materials does not exceed 0.25.
