Abstract
Disclosed herein is a silver halide color photographic light-sensitive material which has a specific photographic sensitivity of 320 or more, and which comprises a support layer and silver halide emulsion layers formed thereon. The material has a film thickness of 22 .mu.m or less, measured from the light-sensitive layer closest to the support layer up to the surface of the material facing away from the support layer. At least one of the silver halide emulsion layers contains a spectral sensitizer represented by the following formula (I): ##STR1## In the formula, R.sup.1 and R.sup.2 are alkyl groups, at least one of which at least one carbon atom bonds together with at least three atoms other than hydrogen atoms, X is an anion, p is 0 or 1, k is 0, 1 or 2, L.sub.1 and L.sub.2 are a methyne group or a substituted methyne group, Z.sup.1 and Z.sup.2 are groups of atoms numerous enough to form a 5- or 6-membered nitrogen-containing heterocyclic ring.
