Abstract

PURPOSE: To let desirable spectral sensitization characteristics be exhibited in the wavelength region of a blue color and make the emulsion stable for high temperature preservation particularly when couplers are contained by making combination use of two kinds of specific sensitizing dyes.
CONSTITUTION: The sensitizing agent of the formula I [X1, Y1 are Se, S, where either one is Se; R1 is (substituted) lower alkyl, (substituted) allyl; L1 is lower alkylene] and the sensitizing dye of the formula II [X2, Y2 are Se, S; L2 is lower alkylene; R2 is (substituted) lower alkyl, (substituted) allyl; R3 thru R6 are H, lower alkyl, alkoxy, hydroxy, halogen, aryl, where not all or R3 thru R6 are simultaneously H] are combined and are contained in a silver halide photographic emulsion. When this photograpic emulsion contains yellow couplers, the effect of less sensitivity change particularyly at the preservation at the retained temperature is markedly shown.
