Method for processing silver halide photographic light-sensitive material |
摘要 |
The present invention provides a method for photographic processing of a silver halide photographic light-sensitive material with high sensitivity and with less fog. This method comprises imagewise exposing a silver halide photographic light-sensitive material and then developing the exposed light-sensitive material in the presence of at least one compound selected from the group consisting of the compounds represented by the following formulas (I)-(IV): <IMAGE> (I) <IMAGE> (II) wherein Z represents a group of atoms necessary to form a condensed aromatic ring which may have a substituent in addition to <IMAGE> R represents a hydrogen atom or a monovalent organic group, R1 represents a hydrogen atom or a substituted or unsubstituted alkyl group and X represents an oxygen atom, a sulfur atom, a selenium atom or >N-R2 wherein R2 represents a hydrogen atom or a substituted or unsubstituted alkyl group; <IMAGE> wherein Y represents a group of atoms necessary to form a heterocyclic ring having two or more nitrogen atoms, Z represents a group of atoms necessary to form a condensed aromatic ring which may have a substituent in addition to <IMAGE> and R represents a hydrogen atom or a monovalent organic group; and <IMAGE> (IV) wherein Y represents a group of atoms necessary to form a nitrogen-containing heterocyclic ring containing no condensed aromatic ring, R represents a hydrogen atom or a monovalent organic group, A represents an arylene group and n is 0 or 1.
