ABSTRACT:
There is disclosed a silver halide photographic light-sensitive material containing a color-developing agent of formula (I) and a coupler of formula (II), in at least one photographic constitutional layer: ##STR1## In formula (I), Z is a carbamoyl, acyl, alkoxycarbonyl, or aryloxycarbonyl group, and Q is a group of atoms that, together with the C, form an unsaturated ring. In formula (II), Cp is a coupler residue, Time is a group that releases PUG upon released from Cp by coupling reaction, PUG is a photographically useful group, and t is 0, 1, 2, or 3. There is also disclosed a silver halide photographic light-sensitive material containing a color-developing agent of formula (I), a dye-forming coupler, and a non-dye-forming coupler (that is unsubstituted on its active site), in at least one photographic constitutional layer. There is further disclosed methods for forming an image using the light-sensitive materials.
