摘要： A method of processing a light-sensitive silver halide photographic material which comprises processing an imagewise exposed light-sensitive silver halide photographic material comprising a support bearing at least one silver halide emulsion layer containing silver halide grains which are sensitized with a sensitizing dye of formula [I]:
wherein:
Z₁ and Z₂, which may be identical or different, are each a group which, together with the nitrogen and carbon atoms to which they are attached, form a substituted or unsubstituted heterocyclic ring which is a thiazole, a benzothiazole, a selenezole, a benzoselenazole, a naphthoselenazole, a benzimidazole, a naphthoimidazole, a pyridine or a quinoline ring;
R₁ and R₂, which may be identical or different, are each an alkyl group, an alkenyl group or an aryl group;
R₃ is hydrogen, a methyl group or an ethyl group;
X₁ ⊖ is an anion; and
ℓ is 0 or 1,
with a colour developer solution comprising an aromatic primary amine color developing agent in the presence of: at least one hydroxylamine derivative of formula [II]
wherein R₂₁ and R₂₂, which may be identical or different, are each hydrogen or an unsubstituted or substituted alkyl group having 1 to 4 carbon atoms, with the proviso that R₂₁ and R₂₂ are not simultaneously hydrogen, or R₂₁ and R₂₂, together with the nitrogen atom to which they are attached, form a nitrogen-containing ring, or a water soluble acid salt thereof; and
at least one nitrogen-containing heterocyclic mercapto compound.
