Abstract
Abstract A silver halide photographic element is described, including a support having on one surface thereof (A) a subbing layer composed of (1) at least one non-hydrophilic polymer layer and (2) a hydrophilic colloid layer containing a dye dispersed therein in a solid state, wherein the hydrophilic colloid layer is coated on the non-hydrophilic polymer layer, and (B) at least one silver halide emulsion layer having a hydrophilic colloid as a binder, wherein the at least one silver halide emulsion layer is formed on the subbing layer, and having on the surface of the support opposite to the side having the silver halide emulsion layer (C) a light-insensitive hydrophilic colloid layer having a hydrophilic colloid as a binder, wherein the silver halide photographic material has a hydrophobic polymer layer which is positioned on the side of the support having the light-insensitive hydrophilic colloid layer and which is located further from the support than the light-insensitive hydrophilic colloid layer, and wherein the light-insensitive hydrophilic colloid layer and the hydrophobic polymer layer do not swell substantially when processed with a processing solution.
