Abstract
Abstract A silver halide photographic light-sensitive member comprising a support having on one side of the support at least one silver halide photographic emulsion layer and on the other side of the support at least one layer containing at least one dye represented by the general formula (I): ##SPC1## wherein Z is a group of atoms required for forming an indolenine nucleus or benzindolenine nucleus; R 1 is a lower alkyl group or a lower alkenyl group; R 2 is an --OXSO 3 - group or an ##EQU1## group wherein X is an alkylene group or an alkenylene group, and Y is a hydrogen atom, an alkyl group, an alkenyl group, an aryl group, an acyl group, or an --OXSO 3 - group; R 3 is a hydrogen atom, a halogen atom, an alkyl group, an alkenyl group, a hydroxy group, an alkoxy group, an alkylthio group, a carboxy group, an alkoxycarbonyl group, an alkoxycarbonylamino group, or an acylamino group; and p is an integer of 1 or 2.
