Zusammenfassung:	Mixtures of symmetrical and asymmetrical 1:2 cobalt complexes of compounds of the formulae and wherein, EACH R1, independently, is hydrogen or (C1-4)alkyl, and EACH R2 and R3, independently, is hydrogen, halogen, (C1-4)alkyl or (C1-4)alkoxy, WHICH COMPLEXES ARE OPTIONALLY IN SALT FORM AND WHICH MIXTURES ARE USEFUL FOR DYEING OR PRINTING SUBSTRATES DYEABLE WITH ANIONIC DYES, E.G., NATURAL AND SYNTHETIC POLYAMIDES SUCH AS WOOL, SILK AND NYLON, POLYURETHANES, POLYOFEFINS MODIFIED TO CONTAIN BASIC GROUPS, LEATHER AND METALS SUCH AS ANODICALLY OXIDIZED ALUMINUM.
