Reactive dyestuff composition for cellulose fibers: reactive dyes with similar hue but different reactive groups and substantivities

摘要

A reactive dyestuff composition containing, as a dyestuff component, at least two different reactive dyestuffs which present similar color hue upon dyeing cellulose and have different reactive groups and different substantivities is disclosed. Preferably, the composition contains at least one reactive dyestuff having either a &bgr;- sulfatoethyl-sulfone group or vinylsulfone group and at least one reactive dyestuff having a halogenated triazine group. The composition is suitable for dyeing cellulose fibers.
