Abstract
Abstract A color photographic silver halide light-sensitive material which prevents formation of color fog is disclosed, containing a negative gradation photographic silver halide emulsion which is substantially of the surface latent image type, and at least one compound represented by the general formula (I): ##STR1## wherein X represents --CONR 1 R 2 , --COR 1 , --SO 2 R 1 , or --SO 3 R 1 and wherein R 1 and R 2 each are selected from the group consisting of a hydrogen atom, a substituted or unsubstituted aliphatic group, and a substituted or unsubstituted aromatic group, and are selected such that may combine together to form a ring.
