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 &gt;2, an average diameter of a sphere of equal volume of .gtoreq.0.3 .mu.m and a diameter of a circle of equal projected surface area of the tabular grains of .gtoreq.0.3 .mu.m, is distinguished by improved sensitivity and an improved sensitivity/grain ratio.

Color photographic recording material

A colour photographic silver halide material with a support, at least one red-sensitive silver halide emulsion layer containing at least one cyan coupler, at least one green-sensitive silver halide emulsion layer containing at least one magenta coupler, at least one blue-sensitive silver halide emulsion layer containing at least one yellow coupler, at least one interlayer Z-1 beneath the lowermost red-sensitive silver halide emulsion layer and/or at least one interlayer Z-2 beneath the lowermost green-sensitive silver halide emulsion layer, in which Z-1 and/or Z-2 contains a silver halide emulsion which contains tabular grains with an aspect ratio of&gt;2, an average diameter of a sphere of equal volume of.gtoreq.0.3 .mu.m and a diameter of a circle of equal projected surface area of the tabular grains of at least 0.3 .mu.m, is distinguished by improved red and/or green sensitivity.

Color photographic silver halide material

A camera-sensitive color photographic recording material which comprises 2 or 3 green-sensitive layers, 2 or 3 red-sensitive layers and 2 or 3 blue-sensitive layers, the blue-sensitive layers being arranged further from the support than the green-sensitive and red-sensitive layers, the layer of low blue-sensitivity or the layer of low blue sensitivity and the layer of medium blue sensitivity being made up of silver halide emulsions containing at least 50 mol-% AgCl and the total silver coating of the material being adjusted as a function of sensitivity to a value which satisfies the following relation:
