Zusammenfassung:A colour photographic silver halide material with at least two blue-sensitive, yellow-coupling silver halide emulsion layers of differing photographic sensitivity, at least two green-sensitive, magenta-coupling silver halide emulsions layers of differing photographic sensitivity and at least two red-sensitive, cyan-coupling silver halide emulsion layers of differing photographic sensitivity, at least one interlayer Z-1 below the lowermost red-sensitive silver halide emulsion layer and/or at least one interlayer Z-2 below the lowermost green-sensitive silver halide emulsion layer, in which material a coupler is additionally used in at least one silver halide emulsion layer, which coupler couples to yield a colour which is not complementary to the spectral sensitisation of the layer concerned, and Z-1 and/or Z-2 contain a silver halide emulsion which has tabular grains with an aspect ratio of >2, an average diameter of a sphere of equal volume of >/=0.3 mu m and a diameter of a circle of equal projected surface area of the tabular grains of >/=0.3 mu m, is distinguished by improved sensitivity and an improved sensitivity/grain ratio.
