Abstract:
A compound of the formula in whichR is substituted or unsubstituted C1-C4alkyl, R1 is hydrogen, X is halogen, Z is phenyl which is substituted by one or more identical or different substituents from the group consisting of sulfo, C1-C4alkyl, C1-C4alkoxy and reactive radicals of the formulae â€”SO2â€”Yâ€ƒâ€ƒ(2a), â€”CONHâ€”(CH2)nâ€”SO2â€”Yâ€ƒâ€ƒ(2b), â€”NHâ€”COâ€”Y1â€ƒâ€ƒ(2d), in whichY is vinyl, &bgr;-chloroethyl, &bgr;-sulfatoethyl, &bgr;-thiosulfatoethyl, &bgr;-acetoxyethyl, &bgr;-phenoxyethyl or &bgr;-phosphatoethyl, Y is a group â€”CHX1â€”CH2X1 or â€”CX1=CH2 and X1 is bromine or chlorine, and n is an integer from 1 to 6; or Z is 1- or 2-naphthyl which is substituted by sulfo or a reactive radical of the formula (2a) defined above; and D is the radical of formula in which (R6)0-3 is 0 to 3 identical or different substituents from the group consisting of C1-C4alkyl, C1-C4alkoxy, halogen, carboxyl and sulfo andY is as defined above; in which (R6)0-3 is as defined above or is a radical of the formula â€”SO2â€”Y,in which Y is as defined above; in which (R6)0-3 is as defined above, in which Y is as defined above; in which (R14)0-2 is 0 to 2 identical or different substituents from the group consisting of C1-C4alkyl, C1-C4alkoxy, halogen, carboxyl and sulfo; andY is as defined above; with the proviso that at least one of the radicals D and Z carries a fibre-reactive radical â€”SO2â€”Y or â€”NHCOâ€”Y1, in which Y and Y1 are as defined above.
