发明名称 Method for processing silver halide photographic material with an alkaline black and white developer
摘要 A method of processing a silver halide photographic material is described, comprising developing an exposed silver halide photographic material with an alkaline black-and-white developer having a pH value of 9.2 to 10 comprising: (1) at least one of hydroquinones, (2) at least one of 3-pyrazolidone-based developing agents, (3) at least one of dialdehyde-based hardening agents, (4) at least one antifoggant selected from the group consisting essentially of indazole-, benzimidazole-, benztriazole- and mercaptothiadiazole-based antifoggants, (5) at least one compound selected from the group consisting essentially of diethylenetriaminepentaacetic acid, triethylenetetraminehexaacetic acid, 1,3-diamino-2-propanoltetraacetic acid, ethylenediaminetetramethylenephosphonic acid, aminotrimethylenephosphonic acid and alkali metal salts thereof, (6) at least one of silver halide solvents, and (7) at least one compound selected from the group consisting essentially of sulfite, bisulfite, and metabisulfite.
