摘要： The invention is accomplished by providing an aqueous dispersion of a photographic coupler by precipitation from a solvent solution by solvent and/or pH shift. A second aqueous dispersion of an activating permanent solvent for the photographic coupler is also provided. The dispersion of activating permanent solvent and photographic coupler are combined to form a combined dispersion which is mixed with a gelatin dispersion of silver halide particles to form a photographic emulsion suitable for casting as a photographic element. In a preferred method of the invention, the activating solvent is incorporated into a dispersion of latex particles prior to being combined with the dispersion of photographic coupler.
