Abstract
Abstract A silver halide color light-sensitive material having excellent properties for a sensitization treatment is described, containing a polymer coupler having an average molecular weight higher than 30,000 and having a polymeric unit derived from a monomeric magenta coupler represented by formula (I): wherein R 1 is hydrogen, chlorine, or a lower alkyl group having 1 to 4 carbon atoms; A is a phenylene group, a -CONH- group, or a -COO- group; B is an unsubstituted or substituted alkylene group, an unsubstituted or substituted aralkylene group, or an unsubstituted or substituted phenylene group; Y is -0-, -NH-, -S-, -SO-, -S0 2 -, -CONH-, -COO-, -NHCO-, or -NHCONH-; Q is a residue of a magenta color-forming coupler which forms a dye through coupling with the oxidation product of an aromatic primary amine developer; and m is 1 when n is 1, and m is 0 or 1 when n is 0.
