Abstract

1469453 Monoazo dyes containing a sulphatoethyl group CIBA-GEIGY AG 4 April 1974 [4 April 1973 8 March 1974] 15037/74 Heading C4P Novel dyestuffs of the formula (wherein n is zero or 1; R is H, optionally substituted alkyl, or cycloalkyl; the A ring may be substituted; and B is a heterocyclic coupling component radical free from water-solubilizing groups and substituted in a position ortho to the azo bridge by an optionally substituted amino group) are prepared by diazotizing an appropriately substituted aniline and coupling with BH. Coupling components of the aminopyrazole, amino-pyridine and amino-pyrimidine series are specified. The dyestuffs are used for printing and, particularly, dyeing of semi-synthetic or, particularly, fully synthetic materials, especially textile fibres. Examples of substrates are polyacrylonitrile and polymers made from acrylontrile and other vinyl compounds, mixed polymers from dicyanoethylene and vinyl acetate, polyurethanes, polyamides, cellulose acetates and, particularly, aromatic polyesters.
