Abstract:
A color photographic silver halide material which comprises 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, wherein at least one of the blue-sensitive silver halide emulsions is spectrally sensitized with a mixture of at least one sensitizing dye of the formula (I) and at least one sensitizing dye of the formula (II): ##STR26##in whichR.sub.1 is an unsubstituted thienyl, unsubstituted pyrrolyl, unsubstituted furany or unsubstituted phenyl,R.sub.2 and R.sub.3 mutually independently are alkyl, sulfoalkyl, carboxyalkyl, --(CH.sub.2).sub.n CON.sup..theta. --COCH.sub.3, --(CH.sub.2).sub.n CON.sup..theta. --SO.sub.2 CH.sub.3, --(CH.sub.2).sub.n SO.sub.2 N.sup..theta. --COOH.sub.3, or --(CH.sub.2).sub.n SO.sub.2 NHSO.sub.2 CH.sub.3,R.sub.4 is H, halogen, benzothienyl or R.sub.1 andM is a cation or anion required for charge equalization; ##STR27##in whichR.sub.5 and R.sub.6 together or R.sub.6 and R.sub.7 together are the remaining members of a fused benzo ring and the residual substituent R.sub.5 or R.sub.7 which is not part of the fused ring is H andR.sub.8 and R.sub.9 have the same meaning as R.sub.2 and R.sub.3,R.sub.10 is unsubstituted thienyl, unsubstituted pyrrolyl, unsubstituted furanyl or unsubstituted phenyl andM has the above-stated meaning.
