ABSTRACT:
A silver halide color photographic light-sensitive material is disclosed. The light-sensitive material comprises a greensen-sitive silver halide emulsion layer which contains a coupound represented by the following formula T and a magenta coupler represented by the following formula M-I: ##STR1## in formula T, R.sub.1 and R.sub.2 each is a hydrogen atom or an alkyl group; R.sub.3 and R.sub.4 each is a hydrogen atom, an alkyl group, an aryl group or a heterocyclic group; R.sub.5 and R.sub.6 each is a hydrogen atom, an alkyl group, an aryl group, an acyl group or an alkoxycarbonyl group; X is a divalent group including a carbon atom as the component of the 6-member ring of formula T; and n is an integer of zero, 1 or 2. In formula M-I, Z is a group of non-metal atoms necessary to form a nitrogen-containing heterocyclic ring; Xs is a hydrogen atom or a splitting off substitutent; and R.sub.9, R.sub.10 and R.sub.11 each is a hydrogen atom or a substituent provided that two or three groups represented by R.sub.9 to R.sub.11 are not hydrogen atoms at the same time. The light-sensitive material is improved in the light fastness of magenta image and prevented in formation of yellow stain in no image formed area.
