Photographic silver halide colour material having improved granularity and dye hue

摘要

A photographic silver halide color print material comprising a support and yellow, magenta and cyan dye image forming layer units comprising at least one silver halide emulsion layer and at least one dye image-forming coupler which material contains a total silver halide coating weight less than 150 mg/m2 (as silver) and wherein the grain size (average volume in cubic microns) of the emulsion(s) is less than 1.0 ( mu m)3 in the yellow image forming unit and less than 0.125 ( mu m)3 in the magenta image forming unit and wherein each layer unit of the material has a dye image-forming efficiency (E) under conditions of use of above 30 where: <IMAGE> wherein the emulsion(s) of the cyan dye image forming layer unit have a silver coating weight less than 50 mg/m2, and an average grain size less than 0.064 ( mu m)3 and comprise means for increasing the speed of the cyan dye image forming unit emulsion(s) to a level sufficient to provide a cyan image having the desired neutral color balance relationship with the yellow and magenta images formed on exposure and processing.
