Abstract

Azo dyes are made on the fibre by coupling thereon an azo coupling component with a diazo compound obtained by diazotizing an anthraquinone compound containing an external diazotizable amino group excluding 1 : 4-amino-oxyanthraquinones containing external amino groups (cf. Specification 396,412). The use of amides or substituted amides of aromatic hydroxycarboxylic acids (cf. Specification 396,429) and the dyeing of cellulose textiles by combining on the fibre a diazotized 1-alkyl-or dialkylamino-4-p-aminoanilinoanthraquinone with a bis-acylacetyldiamine is also excluded. The external amino group may be attached to the anthraquinone nucleus in various ways. Components specified are aminoaryl or aminoaracyl derivatives of 1-amino, 1 : 5- or 1 : 8-diaminoanthraquinone, e.g. 1 : 5-di-(p-amino-phenylamino)-anthraquinone, 1-(p-aminophenylamino)-anthraquinone and 1-amino-5-(p-aminophenylamino)-anthraquinone; 1-amino-, and 1-alkylamino-4-aminoarylaminoanthraquinones, e.g. 1-methyl- or dimethylamino- and 1-(oxyalkylamino) - 4 - (aminoarylamino)-anthraquinones. Coupling components specified are amines and phenols, pyrazolones and b -keto acid derivatives. Components of relatively low molecular weight, e.g. phenol, o- or m-cresol, resorcin, m-phenylenediamine, m-aminophenol, dimethylaniline, m-oxydephenylamine, 1-phenyl-3-methyl-5-pyrazolone and acetoacetic arylides are useful in deying cellulose esters and ethers. The components may be applied in any desired manner (c.f. Specification 300,929, [Class 15 (ii), Dyeing, Processes &c. for]. Dispersions of the components may be prepared according to Specifications 219,349, 224,925, 242,393, 242,711, 269,960, 273,819, 273,820, 322,737, and 323,788, [all in Class 15 (ii), Dyeing, Processes &c. for]. Swelling agents may be employed. A table and examples showing the shades obtained on cellulose acetate with the following additional components are given : 1-amino-4-(3<1>- or 4<1>-aminophenylamino)-anthraquinone and 1 - methyl - 4 - (4<1> - amino)-phenylaminoanthraquinone; Naphthol AS/G, b -naphthol and b -oxynaphthoic acid.
