| titleOfInvention | Blends of couplers with homologous ballasts |
| abstract | Coupler dispersions comprising an aqueous medium having dispersed therein an organic phase comprising (i) a primary photographic coupler comprising a first ballasting group containing at least 5 carbon atoms and (ii) an auxiliary photographic coupler comprising a second ballasting group, wherein the primary coupler and the auxiliary coupler are present in the dispersion at a weight ratio of from 4:1 to 99:1 and the auxiliary coupler differs from the primary coupler solely in that the second ballast group contains 2 or more additional carbon atoms and associated hydrogen atoms relative to the first ballasting group. Such dispersions are substantially free from crystallization on melt holding or on cold storage, provide direct dispersions without such crystallization problems, provide cost or performance improvements by minimizing the proportion of auxiliary coupler needed to eliminate crystallization problems, and provide photographic materials of improved coatability, of lower cost, or of improved performance. |
