Abstract

1:1 and 1:2 metal complexes comprising the unit of the formula ##STR1## wherein A and B, independently, are radicals of diazo or coupling components, with the proviso that when one of A and B is a radical of a diazo component, the other is a radical of a coupling component, T is --SO.sub.2 N(R.sub.1)-- or --N(R.sub.1)SO.sub.2 --, wherein R.sub.1 is hydrogen, C.sub.1-4 alkyl, C.sub.1-4 alkyl substituted by phenyl or carboxy or C.sub.2-4 alkyl substituted in the .beta.--, .gamma.-- or .delta.--position by phenoxy, C.sub.1-4 alkyl, chloro or hydroxy, with the proviso that T is --N(R.sub.1)SO.sub.2 -- when A is the radical of a diazo component and T is --SO.sub.2 N(R.sub.1)-- when B is the radical of a diazo component, Y is --O-- or --COO-- when A is the radical of coupling component and is --O-- or --NH-- when A is the radical of a diazo component, Me is a divalent or trivalent complex-forming metal ion, and rings J may bear one further substituent and ring L may bear one or two further substituents, which complexes contain at least one water-solubilizing group and are useful as dyes for the dyeing and printing of textile and non-textile substrates dyeable with anionic dyes, for example, natural and regenerated cellulose, natural and synthetic polyamides, polypropylene modified to contain basic groups, polyurethanes, anodized aluminum and paper. Also metal-free, mono-metallizable compounds useful the preparation of the 1:1 and 1:2 metal complexes.
