Abstract: Textile materials of polyacrylonitrile, polyamides, polyurethanes, aromatic polyesters or cellulose acetate and triacetate are dyed by the oxidation of an aromatic amine in a process wherein the amine is prepared direct in the treatment liquor by reductive clearage of a water-soluble azo dye whose aromatic coupling component is free from -SO3H groups, and an oxidising agent is allowed to act on the treated textile by conventional methods. The azo dye may be of the formula:- wherein A is a radical of the benzene or naphthalene series B is a phenylene or naphthylene, R1 is H, -OH or alkoxy, R2 is H, alkyl, -COOH, -OH or alkoxy and n is 1 or 2, but may also have the formula:- wherein the group N=C- is a heterocyclic radical R is an aliphatic or aromatic radical and X is an anion. The specified reducing agents are neutral or acid salts of hydrogen sulphide, sulphurous acid or dithionous acid or compounds which split these off as well as glucose, hydrazine or arylhydrazines. The reductive clearage may take place in the presence of a dispersing agent, e.g. a naphthalene sulphonic acid/formaldehyde, and/or carriers at 60-140 DEG C at pH 5-10. The specified oxidising agents are sodium hypochlorite, quinones, quinonimines and quinonimide chlorides. Examples are given and black dyeings are obtained.
