摘要： The production of tabular silver bromide-iodide emulsions and silver bromide-chloride-iodide emulsions with an aspect ratio 32, an iodide content from 1 to 40 mol % and a chloride content from 0 to 20 mol %, by the process steps of (a) silver halide nucleus precipitation, and (b) at least one further precipitation of silver halide, wherein rein at least one aromatic five- or six-membered, heterocyclic compound, which is free from—SH—,—SSO2H— and—SSO2R groups, is added in an amount from 10−9 to 10−4 mol/mol silver during nucleus precipitation or during the precipitation of an inner zone of the silver halide grain which is different from the nucleus precipitate, results in an improved speed/grain size ratio and in an increased stability of a photographic material which contains an emulsion produced in this manner.

摘要： Emulsions having an improved sensitivity/grain ratio are obtained when a silver halide emulsion containing up to 20 mol % of AgI is prepared by the precipitation of a silver halide emulsion A containing up to 100 mol % of AgI and the addition of a silver halide emulsion B which contains up to 40 mol % of AgI, has an average grain size of at most 0.25 .mu.m and is always more soluble in aqueous gelatine solution than emulsion A either due to its grain size or due to its iodide content, this being carried out in the presence of at least two compounds selected from imidazole, histidine (.alpha.-amino-.beta.-imidazolyl-(5)-propionic acid) and other monocyclic, 5- or 6-membered heterocyclic compounds which have at least one ring nitrogen atom, are free from SH groups and form sparingly soluble silver salts in weak acid to neutral aqueous solutions, which salts redissolve at pH>9 when ammonia is added, one of the at least two compounds being imidazole or histidine and at least one other compound being a compound other than imidazole or histidine.
