摘要:
Reactive dyes of formula (1), wherein R1 is hydrogen or unsubstituted or substituted C1-C4alkyl, (R2)s denotes s identical or different substituents from the group halogen, nitro, unsubstituted or halo-substituted C1-C4alkyl, C2-C4alkanoylamino, C1-C4alkylsulfonyl, carbamoyl, sulfamoyl and sulfo, Me is chromium, cobalt or iron, X is chlorine, T is a fiber-reactive radical of formula —NH—(CH2)2-3—SO2—Z (2a), —NH—(CH2)2-3—O—(CH2)2-3—SO2—Z (2b), formula (2c), formula (2d), formula (2e), formula (2f), (R3)0-2 denotes from 0 to 2 identical or different substituents from the group halogen, C1-C4alkyl, C1-C4alkoxy and sulfo, Z is vinyl or a —CH2—CH2—U radical and U is a group that is removable under alkaline conditions, Q is a —CH(HaI)—CH2—HaI or —C(HaI)═CH2 group, Hal is halogen, s is the number 0, 1, 2 or 3 and m, n, r and q are each independently of the others the number 0 or 1, are especially suitable for dyeing synthetic polyamide fiber materials and yield dyeings or prints having good wet-fastness properties.
