Abstract (en)

A silver halide color photographic material having on a support hydrophilic colloidal layers containing at least one light-sensitive silver halide emulsion layer and at least one light-insensitive layer, one of the silver halide emulsion layers being spectrally sensitized with a compound represented by the following general formula (I): <CHEM> wherein Z represents an oxygen atom or a sulfur atom; R1 and R2 each represents an unsubstituted or substituted alkyl group; V1, V2, V3, V4, V5, V6, V7 and V8 each represents a hydrogen atom, a halogen atom, an alkyl group, an acyl group, an acyloxy group, an alkoxycarbonyl group, a carbamoyl group, a sulfamoyl group, a carboxyl group, a cyano group, a hydroxyl group, an amino group, an acylamino group, an alkoxy group, an alkylthio group, an alkylsulfonyl group, a sulfonic acid group or an aryl group, provided that any two adjacent groups among V1 to v8 do not form a condensed ring by combining with each other, and when the Hammett's sigma p value of Vi (i = 1 to 8) is taken as sigma pi (i = 1 to 8), and Y is defined as Y = sigma p1 + sigma p2 + sigma p3 + sigma p4 + sigma p5 + sigma p6 + sigma p7 + sigma p8, Y </= -0.08 in the case of Z = oxygen atom, while Y </= -0.15 in the case of Z = sulfur atom; X represents a counter ion for charge balancing; and n represents the number of counter ions for rendering the total charge of the compound neutral; and additionally containing an effective amount of a water-soluble bromide; and which material further contains at least one dye represented by the following general formula (II) in either a light-sensitive or light-insensitive constituent layer provided that when the dye of general formula (II) wherein n is 2 is incorporated therein, the amount thereof is in a coverage of at least 1 x 10<-><5> mol/m<2>; <CHEM> wherein L1, L2 and L3 each represents an unsubstituted or substituted methine group; Q represents an aryl group containing at least one sulfo or carboxyl group; R3 and R4 each represents -COR5, -COOR5, <CHEM> -CN, or -CF3; R5 and R6 each represents a hydrogen atom, an unsubstituted or substituted alkyl group, or an unsubstituted or substituted aryl group; m represents 0, 1, 2, or 3; n represents 0, 1, or 2; and M represents K or Na.
