Abstract: Navy blue and black dyestuff mixtures, containing one or more thiopheneazo dyestuffs whose diazo component is derived from the 2-aminothiophene series and whose coupling component is derived from the aniline series, and one or more dyestuffs F whose absorption maximum is at a wavelength of 390 to 520 nm, where the amount of the thiopheneazo dyestuffs is 60 to 99% by weight, relative to the total weight of the thiopheneazo dyestuffs and the dyestuffs F in the mixture.

Abstract: Colour photographic material has Ag halide (AgX) emulsion coat(s) on a base, at least one emulsion contg. cyan coupler(s) which are s-triazolo(2,3-a)-pyridine cpds. of formula (I) and/or (II). In formulae, R1 is 1-20C alkyl (opt. substd. and opt. with -O-, -O-CO-, -CO-O or -O-CO-O- gp(s). in the chain), cyclohexyl, 1-4 C alkylcyclohexyl, opt. substd. phenyl, OH, opt. phenyl-substd. 1-10 C alkoxy or opt. substd. phenoxy; R2 is OH, -CH(CN)2, -CH(CN)-COOL1 or -CH(COOL1)2; L1 is H or R1; R3 is CN, carbamoyl, COOH or COOL1; R4 is H or 1-4 C alkyl; R5 is H, halogen, HOSO2 or 1-10 C alkoxy. USE/ADVANTAGE - The prodn. of colour photographs by developing a latent Ag salt image in a prim. aromatic amino developer in the presence of (I) and/or (II) is claimed. (I) and (II) are easy to incorporate in the emulsions and give image dyestuffs with excellent coloristic properties, which are fast to light, diffusion and heat. Compared with the phenol or naphthol derivs., they have a steeper gradient on the short-wave absorption edge and high transparency in the blue region, giving more brilliant coloured for subtractive colour mixing
