Silver halide photographic light-senstive material and method for forming an image

A silver halide photographic light-sensitive material having at least one photographic constitutional layer on a base, wherein one or more of the said photographic constitutional layers contains at least one color-developing agent represented by formula (I) and at least one dye-forming coupler represented by formula (II) in the same layer or different layers:

• ##STR50## wherein Z represents a carbamoyl group, and Q represents a group of atoms required to form an unsaturated ring together with the C,
• (Y.sup.1).sub.n --M--G--(Y.sup.2).sub.m formula (II)
• wherein M represents a coupler component capable of causing coupling reaction at the site where G is bonded with the oxidation product of the color-developing agent represented by formula (I), G represents a group capable of coupling split-off by the coupling reaction with the oxidation product of the color-developing agent represented by formula (I) and is selected from the group consisting of a heterocyclic group, an aryloxy group, a heterocyclic oxy group, an acyloxy group, an alkoxy group, a carbamoyloxy group, an aryloxycarbonyloxy group, an alkoxycarbonyloxy group, an arylthio group, a heterocyclic thio group, an alkylthio group, an alkylsulfonyloxy group, an arylsulfonyloxy group, a carbonamido group, a sulfonamide group, an alkylsulfonyl group, an arylsulfonyl group, an alkylsulfinyl group, an arylsulfinyl group, an arylazo group, and a carbamoylamino group, Y.sup.1 and Y.sup.2 each represent a group having a dissociation group, whose pKa is 1 or more but 12 or less, n is an integer of 0 to 3 and m is an integer of 1 or 2, provided that n+m.gtoreq.1, and when n and m are each 2 or more, Y.sup.1 's and Y.sup.2 's are each the same or different.
