Compounds of the formula <IMAGE> in which A-X- is the radical of a diazo component, X- is ortho to the azo group and is a metallizable substituent or a substituent convertible to a metallizable group, Y is -OH or -NH2, Z is methyl or carboxy, R is hydrogen, halo, methyl or sulfo, and B is the radical of a coupling component of the heterocyclic, non-cyclic active methylene or monocyclic benzene series, which coupling component of the monocyclic benzene series contains an amino and/or hydroxy group, which group(s) may be alkylated or acylated, and -N=N-B is bound to the 3- or 4-position of ring D, which comounds contain at least one water-solubilizing group, and metal complexes thereof, with the proviso that when the compounds are unmetallized, B is other than a monocyclic benzene coupling component radical. The metal complexes are useful as dyes for the dyeing and printing of anionic dyeable substrates such as natural and regenerated cellulose, natural and synthetic polyamides, polypropylene modified to contain basic groups, polyurethanes, anodized aluminum, sized paper and leather.
