Abstract

Abstract A method for continuously processing a silver halide color photographic material comprising a support having thereon at least one silver halide emulsion layer with a color developing bath which contains at least one primary aromatic amine color developing agent, wherein at least one compound represented by formular (I) is present in said silver halide emulsion layer in an amount of from 3 to 10 mol % per mol of coupler in the layer in which the compound is added, and said silver halide color photographic material is processed with said color developing bath where the replenishment rate is from 20 ml to 200 ml per square meter of the silver halide color photographic material processed ##STR1## wherein R 1 , R 2 , R 3 , R 4 , R 5 and R 6 , which may be the same or different, each represents a hydrogen atom, a halogen atom, a sulfo group, a carboxyl group, a cyano group, an alkyl group, an aryl group, an acyl group, an amino group, a sulfonamide group, an alkoxy group, an aryloxy group, an alkylthio group, an arylthio group, an acyl group, an acyloxy group, a carbamoyl group, an alkoxycarbonyl group or a sulfamoyl group, and R 1 and R 2 , and R 4 and R 5 , may together form a carbocyclic ring or a heterocyclic ring; and Z represents a single bond or a divalent organic group.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 272 words
A method for continuously processing a silver halide color photographic material comprising a support having thereon at least one silver halide emulsion layer with a color developing bath which contains at least one primary aromatic amine color developing agent, wherein (1) at least one compound represented by formula (II) is present in said silver halide emulsion layer in an amount of from 3 to 10 mol % per mol of coupler in the layer in which the compound is added and (2) said silver halide emulsion layer contains silver chlorobromide or silver chloride having a silver iodide content of not more than 0.2 mol %, and said silver halide color photographic material is processed with said color developing bath where the replenishment rate is from 20 ml to 120 ml per square meter of the silver halide color photographic material processed: ##STR20## wherein R 1 , R 2 , R 3 , R 4 , R 5 and R 6 , which may be the same or different each represents a hydrogen atom, a halogen atom, a sulfo group, a carboxyl group, a cyano group, an alkyl group, an aryl group, an acyl group, an amino group, a sulfonamide group, an alkoxy group, an aryloxy group, an alkylthio group, an arylthio group, an acyl group, an acyloxy group, a carbamoyl group, an alkoxy-carbonyl group or a sulfamoyl group, and R 1 and R 2 , and R 4 and R 5 , may together form a carbocyclic ring or a heterocycle ring; R 7 represents a hydrogen atom and R 8 represents a methyl group, an ethyl group or an n-propyl group.
Claim 2
Independent Claim 272 words
A method for continuously processing a silver halide color photographic material comprising a support having thereon at least one silver halide emulsion layer with a color developing bath which contains at least one primary aromatic amine color developing agent, wherein (1) at least one compound represented by formula (II) is present in said silver halide emulsion layer in an amount of from 3 to 10 mol % per mol of coupler in the layer in which the compound is added and (2) said silver halide emulsion layer contains silver chlorobromide or silver chloride having a silver iodide content of not more than 0.2 mol %, and said silver halide color photographic material is processed with said color developing bath where the replenishment rate is from 20 ml to 120 ml per square meter of the silver halide color photographic material processed: ##STR20## wherein R 1 , R 2 , R 3 , R 4 , R 5 and R 6 , which may be the same or different each represents a hydrogen atom, a halogen atom, a sulfo group, a carboxyl group, a cyano group, an alkyl group, an aryl group, an acyl group, an amino group, a sulfonamide group, an alkoxy group, an aryloxy group, an alkylthio group, an arylthio group, an acyl group, an acyloxy group, a carbamoyl group, an alkoxy-carbonyl group or a sulfamoyl group, and R 1 and R 2 , and R 4 and R 5 , may together form a carbocyclic ring or a heterocycle ring; R 7 represents a hydrogen atom and R 8 represents a methyl group, an ethyl group or an n-propyl group.
Claim 3
Dependent Claim 54 words
The method for continuously processing a silver halide color photographic material as claimed in claim 1, wherein said compound represented by formula (I) is contained in the silver halide emulsion layer in an amount of from 3 to 5 mol % per mol of coupler in the layer in which the compound is added.
Claim 4
Dependent Claim 41 words
The method for continuously processing a silver halide color photographic material as claimed in claim 1, wherein said silver halide emulsion layer which contains silver chlorobromide or silver chloride has a silver chloride content of from 98 to 100 mol %.
