Abstract
Disclosed is a light-sensitive silver halide color photographic material having at least one light-sensitive silver halide emulsion layer on a support, characterized in that said light-sensitive silver halide emulsion layer contains a cyan coupler represented by formula [I] shown below, and said light-sensitive silver halide emulsion layer and/or a layer contiguous to said light-sensitive silver halide emulsion layer contains a colored cyan coupler represented by the formula [II]: ##STR1## wherein X, R.sub.1 and R.sub.2 are as defined in the specification; ##STR2## wherein (Coup--).sub.c, L, Q.sub.1, Q.sub.2, M, j, and G are as defined in the specification.

A light-sensitive silver halide color photographic material having at least one light-sensitive silver halide emulsion layer on a support, characterized in that said light-sensitive silver halide emulsion layer contains a cyan coupler represented by formula [I] shown below, and wherein at least one layer selected from said light-sensitive silver halide emulsion layer and a layer contiguous to said light-sensitive silver halide emulsion layer contains a colored cyan coupler represented by formula [II]:
- ##STR21## wherein x represents a hydrogen atom or a group capable of being eliminated by a coupling reaction with an oxidized product of an aromatic primary amine color developing agent;
- R.sub.1 represents a naphthyl group or a heterocyclic group (provided that a carbon atom of said heterocyclic group is bonded to the ureido group), or a phenyl group having at least one substituent (with the proviso that when one of said substituents is cyano at the p-position of said phenyl group relative to the ureido group, the four ortho and meta positions of said phenyl group relative to the ureido group cannot have hydrogen atoms at the same time) selected from the group consisting of trifluoromethyl, nitro, cyano, --COR, --COOR, --SO.sub.2 R, --SO.sub.2 OR, ##STR22## (wherein R represents an aliphatic group or an aromatic group, and R' represents a hydrogen atom, an aliphatic group or an aromatic group);
- and R.sub.2 represents an aliphatic group or an aromatic group necessary to impart diffusion resistance to the cyan dyes formed from the cyan couplers represented by formula [I] and the cyan dyes to be formed from said cyan coupler, ##STR23## wherein (Coup--).sub.c represents a cyan coupler residue;
- L represents a divalent linking group connecting the cyan coupler residue to the dye structure moiety;
- Q.sub.1 and Q.sub.2 each represent photographically inactive mono-valent groups;
- M represents a cation or a hydrogen atom;
- j is an integer of 0 or 1;
- and G represents an acyl group or an alkylsulfonyl group having 1 to 8 carbon atoms or an arylsulfonyl group having 6 to 8 carbon atoms.
