Abstract

Process for the preparation of heavy metal-containing azo dyes, characterized in that it accumulates in a di-cyclically coordinated azo-dye containing a co-ordinately hexavalent heavy metal atom per dye molecule, in a slightly acidic, neutral, or alkaline medium, a dye-azo dye. Cyclically metallizing, and because these azo dyes are chosen for the purpose so that the reaction product contains a complex mono- and disazo-dye in the heavy metal atom.
