Abstract

Abstract A silver halide color photographic light-sensitive material is disclosed. The light-sensitive material comprises a support having thereon a photographic layer including a silver halide emulsion layer comprising silver halide grains and a binder and a specific pyrazolone type magenta coupler, a non-light-sensitive layer comprising a binder and a compound of Formula II being a liquid at 15° C., and provided adjacently to the surface of said silver halide emulsion layer closer to sais support, and a layer provided at the outermost position of said photographic layer containing a compound represented by Formula II; ##STR1## wherein R 11 and R 12 are each a secondary or tertiary alkyl group and a number of carbon atoms Contained in the groups represented by R 11 and R 12 is 20 or more in total.
