Abstract
Process for the preparation of metallizable azo dyes and their complex heavy metal compounds, characterized in that an aromatic mine containing a substituent suitable for the formation of metal complexes, or a substituent that can be converted into a metalizable group or can be replaced by this one, and because it is coupled with a 2-amino-naphthalene-compound copulating in position 1, such that it is substituted in the amino group by an organic radical, which contains an appropriate substituent for the participation in complex formation, after which the obtained azo-dye, optionally under generation of the second metallizable group, is treated, preferably in substance, or on the fiber, with means that yield metal.
