Abstract
A process for dyeing or printing cellulosic fiber materials, which comprises using at least one reactive dye of formula ##STR1## wherein R1, R2, R3 and R4 are each independently of one another hydrogen, halogen, sulfo, C1 -C4 alkyl or C1 -C4 alkoxy,
R5 and R6 are each independently of the other hydrogen, halogen, C1 -C4 alkyl, C2 -C4 alkanoylamino, ureido, or C1 -C4 alkoxy which is unsubstituted or substituted in the alkyl moiety by hydroxyl, sulfato or C1 -C4 alkoxy,
Z1 and Z2 are each independently of the other vinyl or the radical --CH2 --CH2 --U, and
U is a leaving group.
