More Information
Summary:This invention relates to a silver halide photographic element with enhanced light absorption and low dye stain. It more specifically relates to a silver halide photographic element containing a dye layered emulsion and a specific class of sensitizing dyes. This invention provides a silver halide photographic element comprising at least one silver halide emulsion comprising silver halide grains which have associated therewith at least an inner dye layer and an outer dye layer wherein the outer dye layer comprises a dye having at least one substituent that has a positive charge, said photographic element further comprising a cyanine dye of formula (I) or (II) (as described in the specification) that is capable of spectrally sensitizing a silver halide emulsion.
