Summary:1:2 Chromium complexes of the formula, I in which R1 is hydrogen, chlorine, bromine, nitro (being meta to the first nitro group), C1-4alkyl or C1-4alkoxy, R2 is hydrogen or nitro, Y is wherein R3 is hydrogen, chlorine, bromine, trifluoromethyl, C1-4alkyl or C1-4alkoxy, and R4 is hydrogen, chlorine, bromine, C1-4alkyl or C1-4alkoxy, and A is a wherein the carbon atom marked with the * is bound to the azo radical, which complexes are in free acid or salt form, and mixtures thereof, are useful for dyeing and printing nitrogen-containing organic substrates, for example, natural and synthetic polyamides such as wool, silk and nylon, polyurethanes, polyolefins modified to contain basic groups and leather, for dyeing metals such as anodized aluminum and in printing lacquers and ball-point pen inks.
