Abstract:
A reactive dye of the formula I wheren is 1 or 2,G.sup.1 is hydrogen or hydroxyl,G.sup.2 is hydrogen or hydroxysulfonyl,G.sup.3 is hydrogen or a radical of the formula ##STR70## R.sup.1 is hydrogen or hydroxysulfonylmethyl, R.sup.2 is hydrogen or hydroxysulfonylmethyl, andD is, when n is 1, a radical of the formula ##STR71## or, when n is 2, a radical of the formula ##STR72## where the ring A may be benzofused, R.sup.3, R.sup.4 and R.sup.5 are each independently of the others hydrogen, C.sub.1 -C.sub.4 -alkyl, C.sub.1 -C.sub.4 -alkoxy, halogen or hydroxysulfonyl, E is hydrogen, a heterocyclic anchor radical or a anchor radical of the aliphatic series, Y is vinyl or a radical of the formula C.sub.2 H.sub.4 --Q, where Q is an alkali-detachable group, and T is a bridge member,with the proviso that at least one hydroxysulfonylmethyl group shall be present in the molecule and that dyes of the formula ##STR73## where n, D, G.sup.7 and G.sup.2 are each as defined above, shall be excluded.
