    Abstract: Reactive dyes of the formula where n is 1 or 2, X is a six-membered halogen-containing nitrogen heterocycle, L1, depending on n, is fluorine, chlorine, C1-C4-alkoxy, phenoxy, C1-C4-alkyl, substituted or unsubstituted phenyl or a bridge member which has one or two hydroxysulfonyl groups, D is the radical of a diazo component of the aniline or naphthalene series which has at least one hydroxysulfonyl group, L2 is hydrogen or substituted or unsubstituted C1-C8-alkyl, L3 is the cationic radical of an aromatic heterocycle which is linked to the pyridone ring via a nitrogen atom, and L4 is hydrogen or C1-C4-alkyl, with the proviso that the number of hydroxysulfonyl groups in the molecule exceeds that of the cationic groups by at least one, are useful for dyeing and printing hydroxyl- or nitrogen-containing substrates.
