A silver halide photographic material is diclosed, comprising a support having thereon at least a photographic emulsion layer and a non-photosensitive hydrophilic colloid layer, the emulsion layer or colloid layer containing at least one type of dye represented by the following general formula (I):
wherein:
R1 represents an alkyl group, aryl group, alkoxy group, aryloxy group, acyl group, carboxyl group, alkoxycarbonyl group, aryloxycarbonyl group, amido group, carbamoyl group, alkylcarbamoyl group, dialkylcarbamoyl group, alkylsulfonamido group, arylsulfonamido group, sulfamoyl group, alkylsulfamoyl group, dialkylsulfamoyl group, arylsulfamoyl group, mono- or dialkylamino group, arylamino group, ureido group, alkylsulfonyl group, arylsulfonyl group, hydroxyl group, cyano group or halogen atom;
R2, R3 and R4 each independently represents a hydrogen atom, halogen atom, alkyl group, alkoxy group, alkylamino group, dialkylamino group, arylamino group or diarylamino group;.
Rs represents a hydrogen atom, alkyl group or benzyl group; Za, Zb and Zc each represents -N = or
wherein R6 represents an alkyl group or aryl group;
n represents 0 or 1; and
at least one carboxyl group, alkylsulfonamido group or arylsulfonamido group is contained in the molecule. The material is irreversibly decolored by photographic processing and the dye has no adverse effect on the photographic characteristics of the emulsion even after the dyed layers have aged.
