ABSTRACT:
The heavy metal complexes of azo dyestuffs of formula ##STR1## where B is hydrogen, chloro or bromo and D is the residue of a diazo component of the benzene or naphthalene series that contains an hydroxyl, carboxyl or amino group in the position ortho to the azo group, are useful to dye substrates, notably wool, in level green and blue shades having good resistance to acid, alkali, light and rubbing.
