    • 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 to form a 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, 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. The use of relatively low levels of specified high-boiling organic solvents enables the direct dispersion of hydrophobic photographically useful materials with low solubility in conventional primary photographic useful solvents without crystallization problems or excessive decomposition.
    • 一种用于直接分散照相的有用材料的方法,包括:(i)水相和(ii)液态有机相在剪切或湍流条件下混合以形成分散在水相中的有机相的分散体; 其中液体有机相包含一种或多种照相用的材料和一种或多种沸点为至少150℃,分子量小于或等于300的有机溶剂,溶剂化变色参数β值大于或等于 至0.50,其中沸点为至少150℃,分子量小于或等于300的溶剂的总和与溶剂化变色参数β值大于或等于0.50的相对于照相的重量比 有用的材料不超过0.25。 使用相对低含量的特定高沸点有机溶剂使得能够在常规的主要照相有用溶剂中直接分散具有低溶解度的疏水照相用材料,而没有结晶问题或过度分解。
