Abstract
A silver halide photographic light sensitive material is disclosed which comprises a support and provided thereon, a hydrophilic colloid layer comprising at least one silver halide emulsion layer and at least one non-light sensitive layer, the hydrophilic colloid layer being hardened with at least one hardener selected from the group consisting of a carboxyl active hardener, a vinylsulfone type hardener, an epoxy type hardener and a triazine type hardener, wherein a silver halide emulsion layer closest to the support of the silver halide emulsion layers contains a dye in the form of dispersed solid particles or a non-light sensitive layer closest to the support of the non-light sensitive hydrophilic colloid layers contains a dye in the form of dispersed solid particles, and the thickness swell percentage of the photographic component layer is 10 to 100%.
