Abstract
1303321 Disperse disazo dyes CIBA-GEIGY AG 20 March 1970 [21 March 1969] 13611/70 Heading C4P The invention comprises disazo dyes, free from acidic water - solubilizing groups, of formula wherein A is phenyl which may be substituted, R is phenyl which may be substituted by halogen, alkoxy or alkyl, X is -O- or -S-, Q is a 1,4-phenylene or -naphthylene substituted as under R above, B is an o- or pphenylene radical which may be further substituted. The dyes are prepared by coupling a diazonium compound of an amine of formula with a phenol. The intermediate aminoazo dyes are prepared by coupling a diazotized aniline with a para-coupling aniline or naphthyl - amine, one or other component containing -X-R. The dyes may be used to colour hydrophobic synthetic textile fibres, e.g. polyester, polyamide, cellulose ester and polyolefin fibres in yellow, red and brown shades.
