Abstract
Silver halide emulsions are prepared by precipitating a silver halide emulsion I on a more sparingly soluble silver halide emulsion II in the presence of a silver halide solvent wherein the emulsion I has been prepared in the presence of a compound inhibiting grain growth.
Claims10
A process for the preparation of a silver halide emulsion in which a fine-grained silver halide emulsion I is blended in the presence of at least one silver halide solvent with a silver halide emulsion II which is less soluble than said emulsion I and in which the blend is held for a sufficient time to effect redissolving of emulsion I and precipitation on emulsion II wherein emulsion I has been prepared by reaction of a soluble silver salt and a soluble halide in the presence of at least one compound inhibiting grain growth.
