摘要:
Claimed are compounds of the formula (I) 1 where the substituents are each as defined in the claims, their preparation, their use as dyes and as a constituent of an inkjet printing ink, and also substrates which have been dyed with such compounds.
摘要:
The disclosed dyes (which are fiber-reactive and are useful for dyeing materials containing OH and/or carboxamide groups) are compounds of the formula (1)Fb--Z.sub.n (1)in which:Fb is the radical of various classes of dyestuffs, including the formazans, azomethines, phthalocyanines, etc., and particularly sulfo group-containing monoazo or disazo dyes of the formulas (a-1) through (a-5):D.sup.1 --N.dbd.N--K.sup.2 -- (a-1)--D.sup.2 --N.dbd.N--(E--N.dbd.N).sub.v --K.sup.1 (a-2)--D.sup.2 --N.dbd.N--(E--N.dbd.N).sub.v --K.sup.2 -- (a-3)D.sup.1 --N.dbd.N--K.sup.0 --N.dbd.N--D.sup.2 -- (a-4)--D.sup.1 --N.dbd.N--K.sup.0 --N.dbd.N--D.sup.2 -- (a-5)in which in which D.sup.1 is a substituted or unsubstituted phenyl or naphthyl radical, D.sup.2 is the radical of a diazo component and K.sup.1, K.sup.2, and K.sup.0 are various coupling components, and E is a middle component.
