    Abstract: Compounds of the general formula I A-B-A (I) where A is a radical of the formula and B is a bridge member of the formula and where R1 and R2 independently of one another are unsubstituted or hydroxy-, C1-C4-alkoxy-, cyano-, C1-C4-alkoxycarbonyl-, di-C1-C4-alkylamino-, chlorine- or bromine-substituted C1-C4-alkyl, cyclohexyl, benzyl, phenylethyl or phenyl, or R1 and R2 together with the nitrogen are morpholino, pyrrolidino, piperidino or N-methylpiperazino, R3 is hydrogen, chlorine, bromine, methyl, ethyl, methoxy, ethoxy or nitro, R4 and R5 independently of one another are hydrogen, C1-C4-alkyl or benzyl, X is oxygen or imino and alkylene is of 2 to 6 carbon atoms and is linear or branched. The compounds of the formula I are particularly suitable for coloring paper pulps.

    Abstract: The dyes have formula (I) in the free acid form in which A is the residue of an aliphatic or carbocyclic amine component, D is the residue of a diazo component, Z is an aliphatic carbocyclic or heterocyclic gp. X is -O- or -COO-, B is X or > N-L, E is -O- or > N-L, L is H or opt. substd. (cyclo)alkyl, aralkyl or aryl gp. R1 is H, Cl, Br, alkyl, alkoxy, nitro, acylamino, carboxy or opt. N-substd carbamoyl or sulphamoyl gp. and R2 is H, Cl, Br alkyl or nitro or R1 and R2 together form a condensed benzene ring. The dyes (I) have good solubility properties and can be obtd. in the form of stable conc. solns. which can be used directly for the prodn. of dye baths and printing pastes. The dyes are esp. useful for dyeing natural and synthetic N-contg. materials such as wool, leather, polyamide and polyurethane fibres. The dyes have good fastness to light, sweat, moisture and washing. Due to the large number of anionic charges they carry, they have good migration properties and give level dyeings. Due to the good solubility properties, they are esp. useful in continuous dyeing processes, e.g. in carpet dyeing.

    Abstract: Basic dyes of the general formula A-B-A I where the substituents A independently of one another are a radical of the formula and B is a bridge member, and in the formula for A R1 and R2 independently of one another are C1-C4-alkyl which is unsubstituted or substituted by hydroxyl, C1-C4-alkoxy, cyano, C1-C4-alkoxycarbonyl, di-C1-C4-alkylamino, benzyl-(C1-C4-alkyl)-amino, chlorine or bromine, or are cyclohexyl, benzyl, phenylethyl or phenyl, or R1 and R2 together with the nitrogen are pyrrolidino, piperidino, morpholino or N-methylpiperazino, R3 is hydrogen, chlorine, bromine, methyl, ethyl, methoxy, ethoxy or nitro, X is oxygen, imino or C1-C4-alkylimino and alkylene is of 2 to 6 carbon atoms and is straight or branched. The novel dyes are mainly used for dyeing paper pulps.

    Abstract: Compounds of the general formula I where B is a bridge member, the radicals R independently of one another are hydrogen or substituted or unsubstituted alkyl, or two radicals R together with the nitrogen are a heterocyclic saturated 5-membered or 6-membered ring, the radicals R1 independently of one another are hydrogen or C1-C4-alkyl, the radicals R2 independently of one another are hydrogen, C1-C4-alkyl or halogen, the radicals R3 independently of one another are hydrogen or substituted or unsubstituted alkyl or together are an alkylene group, and X(-) is an anion. The compounds of the formula I are particularly suitable for dyeing paper.

    Abstract: Chrome complex dyestuffs of formula (I) are new:- In (I) A is an aliphatic or carbocyclic amine residue D is a diazo; Z is an aliphatic; carbocyclic or heterocyclic gp.; X is an -O- or -CO2- gp; B is as X or >N-L; E is an -O- or >N-L where L is H or alkyl, cycloalkyl, aralkyl or aryl, opt. substd. R1 is H, Cl, Br, an alkyl or alkoxy gp., nitro, acylamino or carboxyl or a carbamoyl or sulphamoyl gp. opt. substd by N1, R2 is H, Cl, Br, an alkyl gp. nitro, and R1 and R2 being also able to form together a condensed phenyl gp. (I) are used for dyeing and printing natural or synthetic materials such as wool, leather, polyamide or polyurethanes. Dyeing with (I) have excellent fastness, partic. wet fastness in washing, gassing, and perspiration. (I) have good powers of migration giving regular, level dyeings despite the size of the molecule and the increased number of anionic charges. Because of their excellent solubility (I) are partic. suited to continuous dyeing e.g. of cloth.
