Abstract
The invention comprises monoazo dyes which contain in the molecule the grouping <FORM:0993747/C4-C5/1> wherein R1 is a hydrogen atom or an -O-CO-group and X is a haloquinoxaline residue which possesses at least one halogen atom attached to a carbon atom of the heterocyclic ring. The dyes are prepared by treating appropriate aminoazo dyes or copper complexes thereof with a haloquinoxaline carboxylic acid halide. The dyes may be used to colour wool, silk and synthetic polyamides but are preferably used to colour cellulose materials in the presence of an acid-binding agent. In examples: (1) the monoazo dye 6-acetyl-amino-2-aminonaphthalene-4,8-di-sulphonic acid 1 - (31,51 - disulphophenyl) - 3 - methyl -5-pyrazolone is prepared, treated with aqueous sodium hydroxide solution to saponify the acetylamino group and the aminoazo dye condensed with 2,3-dichloroquinoxaline-6-carboxylic acid chloride: (2) the copper complex of the aminoazo dye of formula <FORM:0993747/C4-C5/2> is condensed with 2,3-dichloroquinoxaline-6-carboxylic acid chloride. Further dyes are specified in a table. Specifications 866,914 and 907,384 are referred to.
