ABSTRACT:
A silver halide photographic emulsion is disclosed which includes a sensitizing dye represented by general formula (I) and a compound represented by general formula (II): ##STR1## The substituents within the general formulae are defined within the specification. The emulsion can be used to prepare a photographic material which has high green-sensitivity which is obtained without expanding the wavelength region of spectral sensitivity in the green sensitive region. Further, the resulting material has these improved results and does not show substantial change of its photographic properties such as sensitivity and amount of fogging during storage.
