More Information
Summary:The invention comprises reactive dyes of formula <FORM:1000801/C4-C5/1> wherein F is an organic dye radical, Q is an -SO2-NR1-, -NR1-SO2-, -CO-NR1- or -NR1-CO- bridge member, R1 being hydrogen or C1-C5 alkyl, A is a six-membered carbocyclic ring, X is a hydrogen or chlorine atom or a methyl group, Y1 is a chlorine atom or an alkylsulphonyl or arylsulphonyl radical, Z is -O-, -S- or =N-CH3, m is 1 or 2 and n is 1, 2 or 3. The dyes may be prepared by condensing a dye or a diazo or coupling component containing an amino or amide group with a compound of formula <FORM:1000801/C4-C5/2> wherein W is a carboxylic or sulphonic acid halide group and if an azo dye component is used forming the dye by the usual coupling reaction. Conversely dyestuff acid halides may be condensed with compounds of the above formula wherein W is an amino group. The dyes may be used to colour amide or hydroxyl group-containing fibres by the usual reactive dye processes. The preparation of monoazo, metallized azo, phthalocyanine and anthraquinone dyes is described in examples.
