摘要

The invention relates to reactive dyes of the general formula (I), in which Y is vinyl or a radical of the formula C2H4Q, Q being a group which can be split in alkaline reaction conditions, Z is hydrogen, C1-C4 alkanoyl or a heterocyclic reactive anchor group which can optionally carry a further chromophore radical and K1 is the radical of a coupling component, provided that K1 is not hydroxy naphthylamine coupled to the hydroxyl group in the o position. The invention also relates to the use of said dyes for dyeing or printing of organic substrates having hydroxy groups or nitrogen atoms, and also to their intermediate products.
