Abstract

Abstract A silver halide color photographic light-sensitive material comprising a support having thereon a silver halide emulsion layer containing at least one kind of compound represented by the following general formula (I): ##STR1## wherein each substituent represented by R 1 , R 2 , R 3 , X, or Ar and m are defined within the specification, said silver halide color photographic light-sensitive material comprises a compound represented by the following general formula (II) in the silver halide emulsion layer containing the compound represented by the above general formula (I) and/or a hydrophilic colloid layer which is positioned at the remoter side than the silver halide emulsion layer from the support: ##STR2## wherein each substituent represented by Y, R 4 , R 5 , R 6 , R 7 or Ar is defined within the specification. The silver halide color photographic light-sensitive material can provide a magenta color image having excellent photographic properties without the occurrence of stain, even when the color photographic material is processed in a processing solution under the running condition. A method of forming a color image using the silver halide color photographic light-sensitive material is also disclosed.
