Photographic material containing a pyridine azo or pyridazine azo cyan dye releasing compound

Claim 1

A colour photographic recording material for the production of colour images by the dye diffusion transfer process. comprising a non-diffusible, colour providing compound (dye releasing compound) associated with at least one light-sensitive silver halide emulsion layer, from which compound a diffusible azo dye is released under the conditions of alkaline development as a function of the development of the silver halide emulsion layer, wherein the azo dye corresponds to the following formula I wherein Q denotes a group for completing a pyridine or pyridazine ring on which a carbocyclic or heterocyclic aromatic ring may be condensed; G denotes OH or NH-SO 2 -R 5 ; R 1 denotes H or one, two or three substituents selected from halogen, alkyl, aryl, carboxyl, alkoxycarbonyl. carbamoyl, cyan, alkoxy, alkylthio, alkylsulphonyl, arylthio and arylsulphonyl; R 2 denotes H or a group with an electron acceptor character arranged in an ortho-position to G; R 3 denotes H, acylamine or a group G' having the same definition as G; R 4 denotes H, SO 2 -NR 6 -R 7 or NH-SO 2 -R 5 ; R 5 denotes alkyl, aralkyl, aryl or NR 6 -R 7 ; R 6 denotes H, alkyl, aralkyl or a group which together with R 7 and the nitrogen atom forms the residue of a cyclic amino group; R 7 denotes H, alkyl, aralkyl, aryl or a group which together with R 6 and the nitrogen atom forms the residue of a cyclic amino group.
