Process for stabilizing photographic silver images

摘要

Excellent image silver stability is obtained without intermediate washing after fixing and without a special finishing bath by a process for stabilizing a silver image produced by exposure, development and fixing of a photographic material containing at least one silver halide emulsion layer, in which, immediately after fixing, the photographic material is subjected to treatment by a stabilizing bath containing a compound corresponding to general formula (I) in which X=Cl, Br R1=H, C1-4 alkyl, C6-10 aryl, R2=CHO, COOH, COONa, CH2COOH, CH2COONa, CONR23, CONHR3, R3=H, C1-2 alkyl, and a compound corresponding to formula II and/or to formula III III in which R3 and R4 may be the same or different and represent H, -NH2, alkyl, alkenyl, cycloalkyl, aryl, alkoxy, alkylthio, alkylsulfonyl, sulfamoyl, acyl, -SH or a heterocyclic group.
