Abstract

Abstract A silver halide photographic light-sensitive material and a process for processing it are disclosed. The light-sensitive material is improved in photographic sensitivity, drying property and anti-roller-mark property and is suitable for the disclosed ultra-rapid processing by an automatic processor in which the photographic material is processed for the time of 20 sec to 60 sec in total. The light-sensitive material comprises a support having on at least one side thereof one or more hydrophilic layers containing gelatin which comprise at least one light-sensitive silver halide emulsion layer. An amount of the gelatin contained in said hydrophilic layer or layers is within the range of from 1.90 to 3.50 g/m 2 and a swelling amount of said hydrophilic layer or layers is within the range of from 30 to 58 g/m 2 when said light-sensitive material is treated in a specific condition for 15 sec. at 35° C.
