Abstract
Abstract A silver halide photographic light-sensitive material providing wash-off relief images having high image density and excellent sharpness is described, comprising a support having thereon an antihalation layer, a silver halide photographic light-sensitive layer, and a hydrophilic colloid layer, said antihalation layer being located between said support and said silver halide photographic light-sensitive layer, wherein at least one silver halide light-sensitive layer or hydrophilic colloid layer contains a compound represented by the formula (I), a compound represented by the formula (II) and a compound represented by the formula (III) ##STR1## wherein R 1 represents hydrogen or a substituted or unsubstituted alkyl group; R 2 represents a substituted or unsubstituted alkyl group; and R 3 represents a substituted or unsubstituted alkyl group.
