摘要： A colour photographic recording material having camera sensitivity, possessing on a transparent support at least one silver halide emulsion layer unit which is sensitive to part of the visible spectrum and consists of at least the following constituent layers:a) a spectrally sensitised silver halide emulsion layer containing an effective quantity of a FAR coupler (coupler, which during coupling releases groups producing fogging nuclei) and optionally a colour coupler, the latter during the colour development process coupling with a dye of which the colour is complementary to the spectral sensitisation of layer a), andb) a fine-grained silver halide emulsion layer having low light-sensitivity, of which the silver halide grains are not spectrally sensitised, being a layer adjacent to layer a),with layer b) containing a colour coupler which during the colour development process couples with a dye of which the colour is complementary to the spectral sensitisation of layer a) and the molar quantity of colour couplers in layer b) being greater than in layer a), is distinguished by improved graininess at higher sensitivity.

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.
