Abstract

A silver halide color photographic emulsion is described, containing at least one sensitizing dye represented by formula (I) and at least one compound represented by formula (II). The use of compounds of formula (I) in combination with compounds of formula (II) permits the spectral sensitization of photographic emulsions without extending the wavelength region of spectral sensitivity, enabling the production of a light-sensitive material of high sensitivity and reduced fog. ##STR1## (The symbols V, W.sub.1, W.sub.2, R.sub.1, R.sub.2, R.sub.3, X, n, R.sub.5, Y, X.sub.1, m.sub.1 and m.sub.2 are as defined in the appended claims).
