Abstract

A process for the manufacture of azo dyestuffs of the formula: A-N=N-B wherein A is the residue of an aromatic carbocyclic or heterocyclic amine and B is the residue of a 6- hydroxy-pyrid-2-one which comprises mixing together in acidic aqueous medium an aromatic carbocyclic or heterocyclic amine ANH2, a 6- hydroxypyrid-2-one and a diazotising agent.
