摘要：
The present invention provides a reactive dyestuff with an alkylthio group and a β-sulfatoethylsulfone group, which is represented by formula (I), wherein D, R, R1, R2, R3, R4, Q, x, and y are defined the same as the specification. The reactive dyestuffs of the present invention not only have characteristics of high solubility, high alkali solubility, and easily being washed off for dyeing cellulose fiber, but also are suitably applied in cold-pad-batch dyeing, continuous-dyeing, printing, and digital printing.
