Abstract
Abstract A silver halide color photographic light-sensitive material containing an unsubstituted or substituted glycoluril as an aldehyde gas scavenger. The silver halide color photographic light-sensitive material of the present invention can avoid the decrease in color density and the formation of fog normally present when the silver halide color photographic light-sensitive material is stored for a long period of time in contact with formaldehyde gas. In addition, the silver halide color photographic light-sensitive material of the present invention has a reduced layer thickness and good film strength.
