Claims
- 1. A silver halide photographic material containing 40-500 mg. per 100 g of silver, of a water-soluble compound comprising a metal selected from ruthenium, rhodium, palladium, osmium, iridium, and platinum and having a molecular weight of at least 100; and 1.2 to 120 mg of a black-and-white silver halide developing agent per 100 g of silver.
- 2. A silver halide photographic material according to claim 1, wherein the cation of said salt of metal is an ammonium ion or an alkaline metal or alkaline earth metal ion.
- 3. A silver halide photographic material according to claim 1, wherein the ligand of said salt of metal is selected from among a hydroxy group, a cyano, H.sub.2 O, a halogen atom, a nitro, SO.sub.3, ammonia and C.sub.2 O.sub.4.
- 4. A silver halide photographic material according to claim 1, wherein said salt of metal is a salt of rhodium, iridium or platinum.
- 5. A silver halide photographic material according to claim 1, wherein said water-soluble compound is added in the photographic material in an amount of 40 mg to 500 mg per 100 g of silver.
- 6. A silver halide photographic material according to claim 1, wherein said water-soluble compound is contained in the silver halide emulsion layer of the photographic material.
- 7. A silver halide photographic material according to claim 1, wherein said developing agent is a 3-pyrazolidone compound or a hydroxybenzene compound.
- 8. A silver halide photographic material according to claim 7, wherein said 3-pyrazolidone compound is selected from among 1-phenyl-3-pyrazolidone, 1-p-tolyl-3-pyrazolidone, 5-phenyl-3-pyrazolidone, 5-methyl-3-pyrazolidone, 1-phenyl-5-methyl-3-pyrazolidone, 1-acetamidophenyl-3-pyrazolidone, 1-phenyl-4,4-dimethyl-3-pyrazolidone, 1-p-tolyl-4,4-dimethyl-3-pyrazolidone, 1-phenyl-4-methyl-3-pyrazolidone, 4-hydroxy-4-methyl-1-phenyl-3-pyrazolidone and 4-hydroxymethyl-4-methyl-1-phenyl-3-pyrazolidone.
- 9. A silver halide photographic material accoring to claim 7, wherein said hydroxybenzene compound is selected from among hydroquinone, catechol, pyrogallol, N-methyl-p-aminophenol, p-.beta.-hydroxyethylaminophenol, p-.alpha.-aminoethylaminophenol and N-methyl-N-(.mu.-sulfoamidoethyl) -p-aminophenol.
- 10. A silver halide photographic material according claim 1, wherein said developing agent is contained in the photographic material in an amount of 11 mg to 110 mg per 100 g of silver.
- 11. A silver halide photographic material according to claim 1, wherein said developing agent is incorporated in the silver halide emulsion layer of the photographic material.
- 12. A silver halide photographic material according to claim 1, wherein said water-soluble compound and said developing agent are incorporated in the same layer of the photographic material.
