Abstract
A method of processing with a developer a silver halide photographic light-sensitive material is disclosed, the material comprising a support and provided thereon, a silver halide emulsion layer comprising silver halide grains having not less than 90 mol % chloride, the emulsion layer or a hydrophilic colloid layer adjacent to the emulsion layer containing a tetrazolium compound, or a hydrazine derivative, and replenisher for developer being supplied to the developer in an amount of not more than 200 ml per m 2 of the material processed, wherein the developer contains a carbonate salt in an amount of not less than 0.2 mol/liter.
Claims
exact text as granted — not AI-modifiedWhat is claimed is:
1. A method of processing a silver halide photographic light-sensitive material comprising a support having provided thereon, a silver halide emulsion layer comprising silver halide grains having not less than 90 mol % chloride, said emulsion layer or a hydrophilic colloid layer provided adjacent to said emulsion layer containing a tetrazolium compound or a hydrazine derivative, with a developer, said developer containing a carbonate salt in an amount of not less than 0.2 mol/liter, a ratio of a potassium ion to a sodium ion in said developer being 0.2:1 to 10:1, said developer being replenished in an amount of not more than 200 ml/m 2 of material processed.
2. The method of claim 1 wherein said ratio of potassium ion to sodium ion in said developer is 0.5:1 to 2:1.
3. The method of claim 1, wherein said developer further contains not less than 1.6×10 -2 mol/liter of boric acid or a borate.
4. The method of claim 1, wherein said developer contains a carbonate salt in an amount of 0.2 to 1.0 mol/liter.
5. The method of claim 3, wherein said developer contains 1.6×10 =2 to 3.3×10 -1 mol/liter of boric acid or a borate.
6. The method of claim 1, wherein said hydrazine derivative is represented by Formula [H] ##STR31## wherein A represents a substituted or unsubstituted aliphatic, aryl or heterocyclic group; B represents an acyl group, an arylsulfonyl group, an alkylsulfinyl group, an arylsulfinyl group, a carbamoyl group, an alkoxycarbonyl group, an aryloxycarbonyl group, a sulfamoyl group, a sulfinamoyl group, an alkoxysulfonyl group, a thioacyl group, a thiocarbamoyl group, an oxalyl group or a heterocyclic group, provided that B may form -N=C(R 9 )(R 10 ) together with A 2 and a nitrogen atom, wherein R 9 represents a substituted or unsubstituted, aryl or heterocyclic group and R 10 represents a hydrogen atom or a substituted or unsubstituted alkyl, aryl or heterocyclic group; and A 1 and A 2 both represent hydrogen atoms or one of A 1 and A 2 represents a hydrogen atom and the other represents an acyl group, a sulfonyl group or an oxalyl group.
7. The method of claim 1, wherein said hydrazine derivative is represented by Formula [Ha] ##STR32## wherein R 11 represents a substituted or unsubstituted aryl or heterocyclic group; R 12 represents ##STR33## wherein R 13 and R 14 independently represent a hydrogen atom, a substituted or unsubstituted alkyl, alkenyl, alkinyl, aryl or heterocyclic group, a substituted or unsubstituted alkoxy, alkenyloxy, alkinyloxy, aryloxy or heterocyclicoxy group, an amino group or a hydroxy group, provided that R 13 and R 14 may form a ring together with a nitrogen atom and R 15 represents a hydrogen atom or a substituted or unsubstituted alkyl, alkenyl, alkinyl, aryl or heterocyclic group; and A 3 and A4 both represent hydrogen atoms or one of A 3 and A4 represents a hydrogen atom and the other represents an acyl group, a sulfonyl group or an oxalyl group.
8. The method of claim 1, wherein said tetrazolium compound is represented by Formula [T] ##STR34## wherein R 1 , R 2 and R 3 a hydrogen atom or a group having a negative or positive Hammett's sigma value (σP); n is represents 1 or 2; and X - represents an anion.Cited by (0)
