ABSTRACT:
A silver halide color photographic light-sensitive material comprising a support having thereon a silver halide emulsion layer containing a magenta color image forming polymer coupler latex which is capable of forming a dye upon coupling with an oxidation product of an aromatic primary amine developing agent and which is a polymer or copolymer having a repeating unit derived from a monomer represented by formula (I) ##STR1## wherein [Q] represents a magenta color image forming coupler residue; Za, Zb, Zc and Zd each represents a substituted or unsubstituted methine group, or --N.dbd.; R.sub.1 represents a hydrogen atom, a lower alkyl group, or a chlorine atom; A represents --NHCO--, --OCO--, or a phenylene group; Y represents --O--, --NH--, --S--, --SO--, --SO.sub.2 --, --CONH--, --COO--, --NHCO--, or --NHCONH--; B represents an unsubstituted or substituted alkylene aralkylene or phenylene group; m represents 0 or 1; and n represents 0 or 1, provided that when n represents 1, m represents 1 and when n represents 0, m represents 0 or 1.
The polymer coupler latex provides color images having good fastness to light, heat, and humidity and improved granularity.
