<p>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, halogen, methyl or sulpho, and B is the radical of a coupling component of the heterocyclic, acyclic active methylene or monocyclic benzene series, which coupling component of the monocyclic benzene series contains an amino and/or hydroxy group which groups may be alkylated or acylated, and -N=N-B is bound to the 3- or 4-position of ring D, which compounds 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.</p> |
