Photographic material with heterocylic azo dye for the silver dye bleach process

Claim 1

A photographic recording material for the silver dye bleach process, which material contains in at least one silver halide emulsion layer, or in a colloidal layer adjacent to said layer or layers, at least one oil-soluble azo dye of the formula ##STR59## wherein D is the group of atoms necessary to complete a 5-membered ring selected from the group consisting of pyrazolyl, imidazolyl, triazolyl, thiazolyl, thiadiazolyl, and isothiadiazolyl rings or the derivatives thereof which are fused with a benzene ring, A is hydrogen, C 1 -C 12 alkyl, C 1 -C 4 alkyl which is substituted by alkoxy, phenoxy, acryl, acyloxy, carbalkoxy, cyano or halogen, or is C 1 -C 4 alkoxy, phenyl, phenyl which is substituted by an electronegative group, or is C 1 -C 4 alkylthio, phenyl-substituted C 1 -C 4 alkylthio, cyano, nitro or halogen, and n is 0, 1, 2 or 3, R 1 is hydrogen, C 1 -C 4 alkyl, hydroxyl, or --NHCOL 1 , wherein L 1 is C 1 -C 20 alkyl or substituted carbamoyl, R 6 is hydrogen or --NR 2 R 3 , wherein each of R 2 and R 3 independently of the other is hydrogen, C 1 -C 8 alkyl or C 1 -C 4 which is substituted by acrylamino, phenyl, alkoxy or hydroxyl, and R 4 is hydrogen, C 1 -C 4 alkoxy or --(OCH 2 CH 2 ) m --OCH 3 , wherein m is 1 or 2.
