Fiber-reactive anthraquinone dyes, their preparation and use

摘要

Three new fiber-reactive 1,4-diamino-anthraquinone dyes are claimed which have the 4-amino group monosubstituted by triazine-containing groups, one of these dyes containing 2 sulfo groups and the others 3. Three new fiber-reactive 1,4-diamino-anthraquinone dyes are claimed which have the 4-amino group monosubstituted by triazine-containing groups. The dyes are of formulae (I)-(III), with (I) having a total of 2 sulfo groups. X1 = F or Cl; X = -CH(Hal)-CH2-Hal or -C(Hal)=CH2; Hal = Br or Cl; Z = vinyl or -CH2CH2Y; Y = Cl, -OSO3H or -OCOMe; and X2 = Cl. Independent claims are also included for preparation of the dyes.
