Silver halide photographic material

Abstract

A silver halide photographic material comprising a support having provided thereon one or more hydrophilic colloid layers, at least one layer of which is a silver halide emulsion layer comprising a silver halide emulsion containing silver halide grains, wherein the silver halide grains contained in the at least one silver halide emulsion layer have a silver iodide content of not more than 0.5 mol %, the melting time of the silver halide photographic material is at least 30 minutes, and the total thickness of constituent hydrophilic colloid layers per each side of the support having thereon the at least one silver halide emulsion layer is less than 3.8 μm.

What is claimed is: 
     
       1. A silver halide photographic material comprising a support having provided thereon one or more hydrophilic colloid layers, at least one of which is a silver halide emulsion layer comprising a silver halide emulsion containing silver halide grains, wherein the silver halide grains contained in the at least one silver halide emulsion layer have a silver iodide content of not more than 0.5 mol %, the silver halide photographic material has a melting time of not less than 45 minutes, and the total thickness of constituent hydrophilic layers per each side of the support having thereof the at least one silver halide emulsion layer is less than 3.8 μm. 
     
     
       2. The silver halide photographic material of claim 1, wherein the at least one silver halide emulsion layer is provided on both sides of the support. 
     
     
       3. The silver halide photographic material of claim 1, wherein at least 50% (projected area) of the silver halide grains contained in the at least one silver halide emulsion layer are composed of tabular silver halide grains having an aspect ratio of at least 3. 
     
     
       4. The silver halide photographic material of claim 1, wherein the silver halide grains contained in all of the silver halide emulsion layers of the photographic material have a silver iodide content of not more than 0.5 mol %. 
     
     
       5. The silver halide photographic material of claim 3, wherein the tabular silver halide grains have a projected area diameter of from 0.3 to 2.0 μm. 
     
     
       6. The silver halide photographic material of claim 3, wherein the tabular silver halide grains have an aspect ratio of from 3 to less than 20. 
     
     
       7. The silver halide photographic material of claim 1, wherein the hydrophilic colloid layers constituting the photographic material have a swelling ratio of 280% or lower. 
     
     
       8. The silver halide photographic material of claim 7, wherein the swelling ratio of the hydrophilic colloid layers constituting the photographic material is from 200 to 280%. 
     
     
       9. The silver halide photographic material of claim 2, wherein the photographic material is a black-and-white X-ray photographic material for medical use. 
     
     
       10. The silver halide photographic material of claim 1, wherein the silver halide photographic material has a melting time of not less than 70 minutes. 
     
     
       11. The silver halide photographic material of claim 1, wherein the silver halide grains contained in the at least one silver halide emulsion layer have a silver iodide content of not more than 0.3 mol %. 
     
     
       12. The silver halide photographic material of claim 1, wherein the silver halide grains contained in the at least one silver halide emulsion layer have a silver iodide content of from 0.01 to 0.15 mol %. 
     
     
       13. The silver halide photographic material of claim 1, wherein the total thickness of constituent hydrophilic layers per each side of the support having thereon the at least one silver halide emulsion layer is less than 3.4 μm.
