Fiber-reactive dyes containing an aniline radical which carries two
different vinylsulfonyl moieties
摘要:
Reactive dyes which are particularly suitable for dyeing and printing cellulose containing fiber materials by the cold padbatch process and which produce, in high dye yield, dyeings and prints having good fastness properties containing the radical of an amine of the formula ##STR1## in which R is hydrogen, halogen, hydroxyl or sulfo, Z is a radical of the formula --CH.dbd.CH.sub.2 or --CH.sub.2 --CH.sub.2 --Y, Y is a detachable group, R' is hydrogen or C.sub.1 -C.sub.4 alkyl which is unsubstituted or substituted by --COOH, --CN, --OH or --SO.sub.3 H, and E is a radical of the formula ##STR2## in which R' and Z are as defined above, alk, alk' and alk" independently of one another are a C.sub.1 -C.sub.6 alkylene radical, U is hydrogen, halogen, hydroxyl, sulfato, C.sub.1 -C.sub.4 alkanoyloxy, cyano, carboxyl, C.sub.1 -C.sub.4 -alkoxycarbonyl, carbamoyl or a radical --SO.sub.2 --Z in which Z is as defined above, V is hydrogen, substituted or unsubstituted C.sub.1 -C.sub.4 alkyl or a radical of the formula ##STR3## in which Z, alk and U are as defined above, and q, r and s independently of one another are an integer from 1 to 6.
