Abstract:
This invention relates to a silver halide photographic material comprising at least one silver halide emulsion comprising silver halide grains having associated therewith: (a) a first dye (Dye 1) that is a cyanine dye capable of spectrally sensitizing a silver halide emulsion and that has at least one anionic substituent; and (b) a second dye (Dye 2) that is not a cyanine dye and that has at least one cationic substituent. Dye 2 has a log P, excluding any counterion, of less than 4.00 and greater than 1.00 or Dye 2 is represented by a dye of formula II as described herein.
