    Abstract: Reactive azo dyes of formula (I) are new: (I): in which n =1 or 2; R = H or OH; and D when n = 1, is a residue of formula (II) or when n = 2, is a residue of formula (III); (III): in which the ring A may be benzoannelated; R , R and R independently = H, 1-4 C alkyl, 1-4 C alkoxy, halogen or hydroxysulphonyl; E = H, an heterocyclic anchoring gp. or an aliphatic anchoring gp.; Y = vinyl or C2H4-Q; Q = a gp. that is split off under alkaline reaction conditions; and T = a bridging member, provided that when n = 1, R = OH and R , R and R each = H, E is neither H nor a residue of formula SO2-Y, W -SO2-Y or CONX-W -SO2-Y, in which Y is as above, W = 1-4 C alkylene and X = H or 1-4 C alkyl.

    Abstract: Formazan dyes of the formula in which n is 1 or 2, Kat is the equivalent of a cation, Me is copper or nickel, X is a radical of the formula CO-O or SO2-O, and Y is vinyl or a radical of the formula C2H4-Q, in which Q is a group which can be eliminated under alkaline reaction conditions, and the ring A is optionally substituted and may be benzo-fused, the ring B is substituted and may be benzo-fused, and the ring C is optionally substituted, their use for the dyeing or printing of organic substrates which contain hydroxyl groups or nitrogen atoms; and new hydrazones.

    Abstract: 2-hydroxyphenyl ureas of formula Q-N(R )-CO-NR R (I) are new. Q = a gp. of formula (II); X = NO2 or NH2; X = NO2, NH2, SO3H, sulphamoyl, 1-4C mono- or dialkylsulphamoyl or -S(O)n-Y; n = 0 or 2; Y = vinyl or C2H4-Q; Q = OH or a gp. eliminated under alkaline conditions; R = H, opt. substd. 1-6C alkyl, opt. substd. with 1 or 2 ether O, imino or 1-4C alkylimino gps. in the chain, or 3-4C alkenyl; R , R = opt. substd. 1-6C alkyl, opt. with 1 or 2 ether O, imino or 1-4C alkylimino gps. in the chain, or opt. substd. phenyl; or R = H or L-N(R )-CO-N(R )-Q; L = 2-8 C alkylene or phenylene; or R +R = (-C2H4)2N-R .

    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.
