A silver halide photographic processing solution comprising at least one polymeric compound inhibiting sludge formation and preventing &ldquo;pi-line&rdquo; artefact, more particularly in radiographic non-destructive testing applications, wherein said polymeric compound comprises at least one monomer unit having a silver complexing moiety and at least one monomer unit having a solubilizing group, and wherein both said silver ion complexing moiety and said solubilizing group are comprised in same or different monomer units.

Silver halide photographic processing solution

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 &lcub;111&rcub; or &lcub;100&rcub; 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.

Processing method providing cold blue-black image tone for black-and-white materials having silver halide grain emulsions
