Process for making photographic emulsions and photographic elements and emulsions containing latent image forming units internally containing sensitizing dye

A process of preparing a photographic emulsion having incorporated therein a plurality of latent image forming units, each of said units being comprised of an agglomeration of silver halide in conductive contact with a spectral sensitizing dye, the process comprising:

• dispersing a spectral sensitizing dye in an organic medium to form an organic dispersion;
• contacting the organic dispersion with an aqueous colloidal dispersion of silver halide grains and providing sufficient agitation to the dispersions to form a series of interfaces between the organic and aqueous phases;
• and
• providing to the dispersions a promoter which facilitates the adsorption of the silver halide grains to the interfaces between the organic and aqueous phases to form the latent image forming units.
