Abstract
The invention comprises dyestuffs of formula <FORM:0818008/IV (c)/1> where X is H or -N=N-R1 and R and R1 are residues of diazo components of the benzene, naphthalene or stilbene series. This may be made by coupling the copper coupler of an appropriate naphthalene-azo-naphthalene dyestuff with the desired diazo component. The copper complex of the naphthalenic starting material may be made by reacting 2-diazo-1-hydroxy - 5 - o - benzene - sulphonyloxnaphthol - 7 - sulphonic acid with an appropriate ammoniacal copper salt solution and saponifying the product. When the products are derived from diazo components containing complex-forming groups such as the salicylic acid grouping and those in o-position to a diazo group, they may be metallized in substance or on the fibre. Indicated diazo components and anilines, o-aminobenzenecarboxylic acids, 1-amino - 2 - methoxybenzenes, naphthylamines, 4-aminoazobenzene sulphonic acids and 4-amino - 41 - nitrostilbene - 2,21 - disulphonic acids. The dyestuffs dye vegetable fibres, such as cotton and regenerated cellulose, in green shades. In examples, illustrative of the preparation of dis-, tris- and pentakis azo dyestuffs and their use in dyeing processes, the diazo compounds used are aniline, 2-amino-4-nitrophenol, o-anisidine, aniline-2-carboxylic and sulphonic acids, 2-naphthylamine-8-sulphonic acid, N - acetylbenzidine - 31 - sulphonic acid, 4,41 - nitramino - stilbene - 2,21 - disulphonic acid, 1 - (41 - aminobenzoylamino) - 4 - phenol-3-carboxylic acid and 4-amino-azo-benzene-41-sulphonic acid, some of the dyeings being after-coppered, chromed or treated with diazotized p-nitraniline and one after-treatment by an in substance coppering process is also described. Specification 802,098 is referred to.
