ABSTRACT:
A process for forming a dye image is disclosed, in which a silver halide photographic light-sensitive material having a silver halide emulsion layer is developed by a color developer comprising an aromatic primary amine and an N,N- dialkylhydroxylamine. The silver halide emulsion layer contains a hydrophobic dye-forming coupler and a compound selected from the group consisting of compounds having a sterically hindered phenol group and polyalkylpiperidine compounds or the water soluble acid salt thereof. The dye image having a high maximum density and a high light-fastness can be obtained when the color developer without benzyl alcohol is used.
