Claims
- 1. A silver halide photographic light-sensitive material comprising a support and at least one layer of silver halide emulsion formed on the support, said emulsion layer containing silver halide grains which have been subjected both to reduction sensitization while growing and to at least one chemical sensitization selected from the group consisting of gold sensitization, each of said grains having at least 5 mol% of silver iodide on a surface thereof, said reduction sensitization being performed in the presence of at least one compound selected from the group consisting of the compounds represented by formula [I]:
- R--SO.sub.2 S--M [I]
- where R is an aliphatic group, an aromatic group, or a heterocyclic group, and M is a cation.
- 2. The silver halide photographic light-sensitive material according to claim 1, wherein said silver halide grains are gold plus sulfur sensitized after subjected to the reduction sensitization.
- 3. The silver halide photographic light-sensitive material according to claim 1, wherein said reduction sensitization is performed by using at least one ascorbic acid compound.
- 4. The silver halide photographic light-sensitive material according to claim 3, wherein said ascorbic acid compound is used in an amount of 5.times.10.sup.-5 mol to 1.times.10.sup.-1 mol per one mol of silver halide.
- 5. The silver halide photographic light-sensitive material according to claim 1, wherein said chemical sensitization is performed in the presence of at least one spectrally sensitizing dye.
- 6. The silver halide photographic light-sensitive material according to claim 1, wherein said silver halide grains are in tabular form.
- 7. The silver halide photographic light-sensitive material according to claim 1, wherein not less than 50% of a total projected area of all silver halide grains are occupied by tabular grains having an aspect ratio of 3 to 8.
- 8. The silver halide photographic light-sensitive material according to claim 1, wherein said silver halide grains have a projected area diameter of 0.5 to 2 .mu.m.
- 9. The silver halide photographic light-sensitive material according to claim 1, containing at least one of yellow, magenta and cyan couplers.
- 10. The silver halide photographic light-sensitive material according to claim 9, containing at least one development inhibitor-releasing DIR coupler.
- 11. The silver halide photographic light-sensitive material according to claim 1, wherein said silver halide is silver iodobromide or iodochlorobromide containing 1 to 30 mol% of silver iodide.
- 12. The silver halide photographic light-sensitive material according to claim 1, wherein the silver halide grain contains 7.5 to 15 mol% of silver iodide on its surface.
- 13. The silver halide photographic light-sensitive material according to claim 1, wherein the silver halide grain contains 10 to 15 mol% of silver iodide on its surface.
