    Abstract: Reactive dyes useful for dyeing or printing hydroxyl- or nitrogen-containing substrates have the formula (I) where Rg is a radical of the formula Ar is the radical of a benzene or naphthalene ring, Z1 and Z2 are each hydrogen, substituted or unsubstituted C1-C4-alkyl, substituted or unsubstituted phenyl, C1-C4-alkoxy, carboxyl, C1-C4-alkoxycarbonyl, cyano, halogen or hydroxysulfonyl, Z3, Z4 and Z5 are each hydrogen, substituted or unsubstituted C1-C4-alkyl or substituted or unsubstituted phenyl, U is a group which is detachable under alkaline reaction conditions, X is in case a) the radical of a chromophore or in case b) the radical of a coupling component to which may additionally be attached, via an azo bridge, the radical of a diazo component and which may have additional reactive groups, and L is in case a) a bridge member or in case b) an azo bridge.
