摘要:
A silver halide color photographic material comprising a support having formed thereon at least one silver halide emulsion layer containing a pyrazoloazole series magenta coupler having at least one group expressed by the formula [S] below at a position other than the coupling active position.--(A).sub.n --L--B [S]wherein A represents a substituted or unsubstituted alkylene group, a substituted or unsubstituted cycloalkylene group, a substituted or unsubstituted arylene group, or a substituted or unsubstituted aralkylene group, in which in the main chain of said alkylene group, cycloalkylene group, arylene group, or aralkylene group, --O--, --S--, --CO--, --CO.sub.2 --, --OCO--, ##STR1## may be contained; L represents ##STR2## B represents a hydrogen atom or a substituted or unsubstituted alkyl or aryl group which does not contain therein --SO.sub.2 --; n is 0 or 1; and R and R' each represents a hydrogen atom, a substituted or unsubstituted alkyl group, or a substituted or unsubstituted aryl group. In the above, in the case that the pyrazoloazole series magenta coupler is a 1H-pyrazolo[5,1-c][1,2,4]triazole derivative, A does not represent an aralkylene group containing an arylene group directly connected to L. The silver halide color photographic light-sensitive material has improved coloring properties.
