摘要：NEW MATERIAL:Bisazo compd. of formulaI[where X is -CH=CH2, -CH2CH2R (R is a group which can be removed with alkali); Y is phenylene or naphthylene; n is 2 or 3]. USE:The compd. is useful as a reactive dye for textile material, esp. for dyeing cellulose fibre in black color. Preferred cellulose fibres are cotton, regenerated cellulose and other vegetable fibres such as linen, hemp and jute. The polyamide fibres are natural and synthetic fibres such as wool, silk, polyamide-6, and polyamide-11. PREPARATION:The compd. is prepared by diazotizing a polychloroaniline deriv. of formula II and coupling the resultant diazo compd. with a monoazo compd. shown by formula III in a free state. The monoazo compd. of formula III is prepared by diazotizing an amine of formula IV and coupling it with 1-amino-8- hydroxynaphthalene-3,6-disulfonic acid.
