Abstract

1422986 Photographic silver halide coupler containing emulsions EASTMAN KODAK CO 24 May 1973 [25 May 1972] 24841/73 Heading G2C A photographic silver halide emulsion contains finely divided particles comprising a colour coupler and a coupler solvent of the Formula:- where each R is 3-15C alkyl and each n is 0, 1,2, 3 or 4. The colour coupler may be dissolved in an organic solvent system comprising a coupler solvent of the Formula above and the resulting solution may be dispersed in an aqueous hydrophilic colloid solution which may then be added to a silver halide emulsion. The organic solvent system may additionally comprise a low boiling auxiliary solvent having a water miscibility not exceeding 6-5 parts/100 parts water and a boiling point of 76‹-205‹C.
