Abstract
A silver halide photographic emulsion is disclosed. The emulsion includes a silver halide emulsion which has dispersed therein at least three types of sensitizing dyes. The emulsion includes at least one dye represented by the formula (I), at least one dye represented by the formula (II) and at least one dye represented by the formula (III). Each of the structural formulae and their substituents are defined within the specification. The resulting silver halide photographic emulsion shows a small decrease in the inherent sensitivity of the silver halide due to the sensitizing dye used.
