Abstract:
A color photographic silver halide material comprising at least one blue sensitive silver halide emulsion layer containing at least one yellow coupler, at least one green-sensitive silver halide emulsion layer containing at least one magenta coupler, and at least one red-sensitive silver halide emulsion layer containing at least one cyan coupler, and at least one of the blue-sensitive silver halide emulsions is doped with mercury and is spectrally sensitized with a sensitizing dye of formula (I) ##STR21## wherein X.sub.1 and X.sub.2, independently of each other, denote O, S, Se or NR,R denotes alkyl or carboxyalkyl,R.sub.1 and R.sub.2 or R.sub.2 and R.sub.3 denote the remaining members for the completion of a phenanthro- or anthraazole ring, and the remaining R.sub.1 or R.sub.3 radical denotes a hydrogen atom,R.sub.4 and R.sub.5, independently of each other, denote a hydrogen atom, alkyl or aryl, orR.sub.4 and R.sub.5 jointly denote the remaining members of an unsubstituted or substituted benzazole, naphthazole, phenanthro-or anthraazole,S.sub.1 and S.sub.2, independently of each other, denote alkyl, sulphoalkyl or carboxyalkyl, andM.sup.+ denotes a cation which is possibly necessary for charge equilization.
