ABSTRACT:
Colour photographic silver halide material with at least two blue-sensitive yellow-coupling, two green-sensitive magenta coupling and two red-sensitive cyan coupling silver halide emulsion layers of differing photographic sensitivity, in which the silver halide emulsion of the highest sensitivity blue-sensitive and the highest sensitivity green-sensitive layers have an iodide content of .ltoreq.4 mol % and an average particle size of .gtoreq.0.65 .mu.m and the silver halide emulsions of the lowest sensitivity blue-sensitive and the lowest sensitivity green-sensitive layers have an iodide content of .gtoreq.8 mol % and an average particle size of .ltoreq.0.3 .mu.m and which material contains at least one DIR compound in an effective quantity, the inhibitor of which has diffusibility of .gtoreq.0.4, is characterised by great sharpness and very good colour separation.
