Abstract
A silver halide color photographic light-sensitive material which comprises a support having thereon photographic constituting layers comprising blue, green and red sensitive silver halide emulsion layers, and a light-insensitive hydrophilic colloidal layer, wherein the photographic constituting layers contain, in combination or separately, at least one compound represented by the following formula (1): ##STR1## wherein R.sup.1, R.sup.2, and R.sup.3 represent specific groups, and L.sup.1, L.sup.2, and L.sup.3 each independently represents methine; and PA1 at least one compound selected from the group consisting of the compounds represented by the following formulas (2) and (3): EQU A.sup.1 .dbd.L--Q (2) EQU A.sup.1 .dbd.L--A.sup.2 (3) PA2 wherein A.sup.1 or A.sup.2 each independently represents an acidic nucleus, Q represents aryl or a heterocyclic ring, and L represents methine. The light-insensitive hydrophlic colloidal layer exhibits antihalation effect.
