发明名称 Method of developing silver halide photographic material
摘要 A silver halide photographic material which contains a light-sensitive silver halide emulsion and an internally fogged silver halide emulsion is development-processed in the presence of at least one compound selected from the group consisting of compounds represented by the general formulae (I) and (II) and at least one azaindene having a mercapto group to exhibit high photographic speed, high contrast and high maximum image density: R1-(R3)lX}nR3'-R2 (I) wherein R1 and R2 each represents a hydrogen atom, an aryl group, an aryl group, or a heterocyclic group; R3 and R3' each represents an alkylene group, an arylene group, a heterocyclic group; X presents <IMAGE> <IMAGE> +TR C(R4)2; R4 represents a hydrogen atom or -R5-Y}mR5'-R6; R5 and R5' have the same meanings as R3 and R3'; R6 has the same meaning as R1 and R2; Y represents <IMAGE> +TR <IMAGE> R7 has the same meaning as R1 and R2; l represents 0 or 1, n represents an integer of 1 to 110, and m represents an integer of 0 to 10, and at least one X therein must be a sulfur atom: <IMAGE> (II) wherein Q represents atoms necessary to form a heterocyclic ring, and A represents an alkyl group, or an aryl group.
