ABSTRACT:
Disclosed is a silver halide color photographic material comprising a support having thereon at least one silver halide emulsion layer containing a cyan dye forming coupler and a polymer latex, the polymer latex is derived from a monomer represented by the following general formula (A): ##STR1## wherein R.sub.1 represents a hydrogen atom or an alkyl group having from 1 to 4 carbon atoms; L.sub.1 represents --CONH-- or ##STR2## p represents an integer of from 1 to 4; and q represents an integer of from 1 to 30.
The silver halide color photographic material provides a cyan color image without accompanying decrease in color density even when it is processed with an exhausted bleaching or bleach-fixing solution or a bleach or bleach-fixing solution having an weak oxidizing power. Further, the cyan color image is prevented from the occurrence of stain due to irradiation to light for a long period of time after processing.
Also, the polymer latex may contain, as a copolymer component, a repeating unit derived from a monomer represented by the following general formula (B): ##STR3## wherein R.sub.2 represents a hydrogen atom or an alkyl group having from 1 to 4 carbon atoms; L.sub.2 represents --COO-- or --CONH-- or a phenyl group; L.sub.3 represents --OCO--, --COO--, --NHCO-- or --CONH--; Y.sub.1 and Y.sub.2 each represents a straight chain or branched chain alkylene group having from 1 to 12 carbon atoms; and h, i and j each represents 0 or 1, when j is 0, X represents a hydrogen atom or an alkali metal atom and when j is 1, X represents --COOH, --SO.sub.3 H, --OPO(OH).sub.2 or a metal salt thereof.
