A photographic material is disclosed containing in a non-light sensitive layer above the emulsion layer an anti-sludging compound corresponding to following general formula (I) : <CHEM> wherein Ball represents a ballast group, L represents a divalent linking group and Z represents the necessary atoms to close a heterocyclic ring with the proviso that said heterocyclic ring contains no mercapto substituent. The divalent linking group is preferably chosen from the list of -O-, -S-, -CO-NR1-, -NR2-CO-NR3-, - SO2-NR4-, -O-CR5R6-CO-NH- wherein each of R1, R2, R3, R4, R5 and R6 represents hydrogen, alkyl or aralkyl. The heterocyclic ring is preferably chosen from the list of imidazole, benzimidazole, 1,2,3-triazole, 1,2,4-triazole, benzotriazole, tetrazole, indazole, uracil and hydantoin. The non-light sensitive layer, wherein the anti-sludging compound is added, is preferably the top protective layer.
