Process for preparing a silver halide emulsion.

摘要

A process for preparing a silver halide emulsion is disclosed, which comprises dissolving one or more substantially water-insoluble photographic additives in a solution of an organic solvent containing a surface active agent having a hydrophilic -SO3 or -OSO3 group wherein said organic solvent is an alcohol, and then adding the resulting solution to a silver halide emulsion. A small amount of a base, or small amounts of a base and an acid may optionally be present in the mixed solution of the organic solvent and the surface active agent prior to adding the one or more substantially water-insoluble photographic additives.
