Abstract
Abstract There is disclosed a silver halide photographic material having the improved drying, anticurl and pin hole properties. The photographic material comprises (a) a support, (b) at least one silver halide emulsion layer containing hydrophilic colloid as a binder provided on one side of the support (side A), and (c) at least one light-insensitive layer containing hydrophilic colloid as a binder provided on the side of the support opposite from the side with the silver halide emulsion layer (side B), wherein a weight ratio of the hydrophilic colloid contained in the at least one light-insensitive layer on side B to the hydrophilic colloid in the at least one silver halide emulsion layer on side A is 0.3 or greater, and the light-insensitive layer on side B has a water content of 0.2 g or less per gram of hydrophilic colloid after finishing a rinsing step in development processing.
