Abstract
A silver halide color photographic material is disclosed, comprising a support and at least silver halide emulsion layers on the support, wherein at least one of said emulsion layers contains at least one 2-equivalent 5-pyrazolone polymer coupler and at least one of the other emulsion layers contains at least one phenol cyan coupler having an acylamino group in the 5-position and a ureido group in the 2-position. The present material is advantageous over conventional materials in that the color balance of the image dyes remains unchanged over long periods of time.

A silver halide color photographic material comprising a support and at least two silver halide emulsion layers on the support, wherein at least one silver halide emulsion layer contains at least one 2-equivalent 5-pyrazolone polymer coupler and at least one other silver halide emulsion layer contains at least one phenol cyan coupler which is substituted with an acylamino group in the 5-position and with a ureido group in the 2-position, wherein the 2-equivalent 5-pyrazolone polymer coupler has a repeating unit represented by formula (II) and is derived from a monomer coupler represented by formula (I) ##STR7## wherein R.sub.1 represents a hydrogen atom, a lower alkyl group having from 1 to 4 carbon atoms, or a chlorine atom,
- A represents --CONH--, --COO--, --O--, or a phenylene group,
- B represents an unsubstituted or substituted straight or branched alkylene group, aralkylene group, or phenylene group,
- Y represents --CONR'--, --NR'CONR'--, --NR'COO--, --NR'CO--, --OCONR'--, --NR'--, --COO--, --OCO--, --CO--, --O--, --SO.sub.2 --, --NR'SO.sub.2 -- or --SO.sub.2 NR'--, wherein R' represents a hydrogen atom or substituted or unsubstituted aliphatic group or aryl group, and when two or more R's are present in one molecule, R's may be same or different,
- n is 0 or 1,
- m is 0 when n is 0, or 1 when n is 1, and
- Q represents a 2-equivalent magenta coupler group forming a dye when coupling with an oxidized product of an aromatic primary amine developing agent.
