Abstract
A silver halide color photographic light-sensitive material is disclosed, in which dye images having a high fastness against heat, moisture and light. The light-sensitive material comprises a support having there on a silver halide emulsion layer containing a coupler represented by the following formula I; ##STR1## wherein Za is a --C.dbd. group or a --C.dbd. group, Zb is a nitrogen atom or a ##STR2## group and Zc is a nitrogen atom or a ##STR3## group, provided that when Zb is a nitrogen atom, Za and Zc are the ##STR4## group and the ##STR5## group, respectively, and when Zc is a nitrogen atom, Za and Zb are the ##STR6## group and the ##STR7## group, respectively; R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5, R.sub.6 and Y are each a hydrogen atom or a substituent; X is a hydrogen atom or a substituent capable of splitting off upon reaction with the oxydation product of a color developing agent; n and m are each 1 or 0, provided that m+n is 1.
