    摘要： Reactive dyes of formula wherein R1 and R2 are each independently of the other hydrogen or unsubstituted or substituted C1-C4alkyl, A is C2-C8alkylene interrupted by oxygen, X is halogen, and Y is a fiber-reactive radical of formula (2) —SO2—Z  (2) wherein Z is vinyl or a radical —CH2—CH2—U and U is a group removable under alkaline conditions, are suitable especially for dyeing cotton and yield dyeings having good allround properties.
