ABSTRACT:
A method of forming a color image comprising developing a silver halide photographic light-sensitive material with a developing solution containing an aromatic primary amine is disclosed. The developing is carried out in the presence of a coupler represented by the general formula (I) described below and/or a polymer coupler which is a polymer or copolymer having a repeating unit derived from a vinyl monomer containing a part represented by the general formula (I) described below in its molecule: ##STR1## wherein R.sub.1 and R.sub.2, which may be the same or different, each represents a hydrogen atom or a substituent; and X represents a hydrogen atom or a group capable of being released upon coupling.
The magenta color forming coupler represented by the general formula (I) or the polymer coupler containing the part represented by the general formula (I) has a good color forming property and provides a magenta color image having an excellent spectral absorption property free from subsidiary absorptions in the region around 430 nm and good fastness. A silver halide photographic light-sensitive material containing the magenta coupler is also disclosed.
