Photographic material having enhanced light absorption

摘要

This invention comprises a silver halide photographic material comprising at least one silver halide emulsion comprising silver halide grains having associated therewith at least two dyes:(a) a first dye that has at least one anionic substituent and that is capable of spectrally sensitizing a silver halide emulsion; and(b) a second dye that absorbs light at an equal or shorter wavelength than the first dye and that has at least one cationic substituent and that is highly fluorescent.
