Abstract:
A color photographic silver halide material which can be developed to form a negative, and which comprises a support, at least one blue-sensitive silver halide emulsion layer which contains at least one yellow coupler, at least one green-sensitive silver halide emulsion layer which contains as least one magenta coupler, and at least one red-sensitive silver halide emulsion layer which contains at least one cyan coupler, at least 95 mol % of the silver halides of which contains AgCl, and the material contains at least one light-sensitive silver halide emulsion layer which contains at least one compound of formulae (I) (II) and (III):[IrCl1F6-n]2âˆ’M2+â€ƒâ€ƒ(I) wherein n is 0 or an integer from 1 to 6 and M2+ is 1 or 2 cations with a total number of 2 positive charges,[Fe(CN)6]mâˆ’Mm+â€ƒâ€ƒ(II) wherein m is 2 or 3 and Mm+ is 1 to 3 cations with a total number of m positive charges, wherein o is 0, 1 or 2 and R is an alkyl, aryl or aralkyl.
