摘要:
A process for dyeing cellulosic fibre materials, wherein the fibre material is brought into contact with at least two dyes from the group of formulae (1), (2), (3) and (4) wherein A is hydrogen or a radical of formula (5), R1, R2, R3 and R4 are each independently of the other halogen, C1-C4alkyl, C1-C4alkoxy, nitro, benzoylamino which is unsubstituted or substituted in the phenyl ring, or unsubstituted or substituted amino, n, m, r and s are each independently of the others the number 0, 1, or 2, and p is the number 0, 1, 2, 3 or 4, produces level, tinctorially strong dyeings.
