Abstract (en)
[origin: EP1104893A1] A method has been described for processing an exposed black-and-white silver halide photographic film material comprising in a hydrophilic light-sensitive layer thereof a binder and silver halide grains being ä111ü or ä100ü tabular silver bromo(chloro)iodide or silver chloro(bromo)iodide grains having an average aspect ratio of from 1.2 to 50 and having a silver iodide content of less than 3 mole % based on silver with at least part of it at their grain surface, said method comprising the steps of developing in a developer, fixing in a fixer, rinsing and drying, characterized in that in said developing step the developer comprises an alkali soluble agent having preventing silver dissolution properties, being a mercapto azole compound as presented herein.
