Abstract
Abstract A silver halide photographic light-sensitive material suitable for super rapid processing in not more than 60 seconds is disclosed, which comprises a transparent support having coated thereon gelatin in a total coating amount of 1.7-2.5 g/m2 per one side of the support and a photosensitive layer containing photosensitive silver halide grains, the silver halide grains being silver iodobromide having a silver iodide content of not more than 0.6 mol%.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
83 words
A silver halide photographic light-sensitive material comprising a transparent support having coated thereon gelatin in a total coating amount of 1.7-2.5 g/m 2 per one side of the support and one or more hydrophilic colloid layers at least one of which is a photosensitive layer containing photosensitive silver halide grains, said silver halide grains being silver iodobromide having a silver iodide content from 0.01 to 0.4 mol% and a swelling ratio determined by free-drying of said hydrophilic colloid layer or layers being 200-280%.
Claim 2
Dependent Claim
