Abstract (en)
The invention is directed to a method for producing a silver halide photographic emulsion comprising the step of reacting a water-soluble silver salt and at least one water-soluble halide salt containing chloride or bromide in aqueous solution in the presence of an organic Grain Growth Modifier (GGM) compound,-containing a halide X, which halide is not released in the form of an ion, to form light-sensitive silver halide grains having a silver halide content of a least 50 mole %, said grain growth modifier compound being water-soluble with a solubility > 4 mmole per litre, and being selected from the group of compounds with an aliphatic or cyclo-aliphatic backbone R to which is attached one or more halide groups and at least one polar group.
