Abstract

333,260. Imperial Chemical Industries, Ltd., Brightman, R., and Wellacott, W. L. B. March 5, 1929. Divided on 331,839. Disazo dyes for dyeing regenerated cellulose in even shades are made by tetrazotizing 3 : 3'-diaminodiphenylurea or a derivative thereof other than a carboxylic or sulphonic acid and coupling with a phenol or naphthol sulphonic or carboxylic acid (1 mol.) and a naphthylamine-, naphthol-, dihydroxynaphthalene, or aminonaphthol-sulphonic acid or an N-substituted derivative thereof (1 mol.). The same dyestuffs may be obtained by treating with phosgene equimolecular parts of the dyestuffs m-nitraniline or m-aminoacetanilide (or derivatives other than carboxy or sulphonic) # a phenol or naphthol carboxylic or sulphonic acid (reduced or hydrolyzed) and m-nitraniline or maminoacetanilide (or derivatives other than carboxylic or sulphonic) # a naphthylamine, naphthol-, dihydroxynaphthalene- or aminonaphtholsulphonic acid or an N-substituted derivative thereof (reduced or hydrolyzed). In examples the following components are specified: 3 : 3<1>-diaminodiphenylurea, m-nitraniline or m-aminoacetanilide and 4-nitro-2-anisidine; salicylic acid, 2 : 8 : 6-acid, phenyl-2 : 8: 6-acid; 1 : 5 : 7-a.cid, benzoyl-J-acid, o-cresotinic acid, benzoyl-2: 8: 6- acid, chromotropic acid, N.W. acid, 2-naphthol-7- sulphonic acid and phenyl-J-acid. Specification 10380/13 is referred to in the Provisional Specification.
