    Abstract: Nickel complexes, obtained by heating one or more compounds of the general formula I I where R1 is hydrogen, unsubstituted or substituted alkyl, cycloalkyl, aralkyl, hetaralkyl, aryl or hetaryl, R2 is hydrogen or methyl and X is fluorine, chlorine, bromine or phenoxy, and the ring a may additionally carry fused rings or be substituted and, if R1 is isopropyl or phenyl and the ring a is unsubstituted, R2 is hydrogen, in an organic solvent, in the presence of an acid acceptor and of a nickel donor, are exceptionally suitable for dyeing, in particular, cellulosic fibers.

    Abstract: Dye formulations for dyeing and printing cellulose and cellulosic textile material which in addition to conventional components contain a dye of the general formula (I): (I) in which D is the radical of a diazo component; R is hydrogen, C1 to C7 alkyl, phenyl or phenyl bearing methyl as a substituent; X is cyano, carbamoyl or substituted carbamoyl; R1 is hydrogen or an aliphatic, cycloaliphatic, araliphatic or aromatic radical; R2 is hydrogen or an aliphatic, cycloaliphatic or araliphatic radical; R3 and R4 independently of one another have the same meanings as R1 and R2; and R1-N-R2 and R3-N-R4 independently of one another are saturated heterocyclic radicals.

    Abstract: Thermoplastics are coloured with dyes of formula (I): where A' is a gp. A or a gp. (II) D is the residue of a diazo component, R is H, alkyl or (methyl)phenyl, X is H, carbamoyl or CN, Z is a (cyclo) alkylene, aralkylene or arylene gp., where the alkylene gp. may be interrupted by O, S or N-substd. imino, and A is H, (substd.) (cyclo)alkyl, aralkyl, phenyl or acyl or may together form a 5-7 membered heterocyclic ring with N. (I) are used for dyeing thermoplastics in bulk at is not >300 degrees C, e.g polystyrene, hard PVC, polyethylene, polyamides, polyesters, polycarbonates, styrene-butadiene copolymers and ABS copolymers. (I) are stable to heat. They have up to 3.5 x the colour strength of dyes normally used for dyeing in bulk.

    Abstract: An azo dye of the general formula (1) where A is cyano or carbamoyl, R is hydrogen, alkyl or phenyl, R1 is hydrogen, bromine, chlorine or nitro, R2 is hydrogen, chlorine, bromine, nitro, methyl, trifluoromethyl, sulfamoyl, N-monoalkyl- or N,N-dialkylsulfamoyl (where alkyl is of 1 to 4 carbon atoms), or a sulfonic acid phenyl ester, methylphenyl ester, chlorophenyl ester or methoxyphenyl ester group, R3 is hydrogen or alkyl of 1 to 8 carbon atoms which may be interrupted by oxygen and may be substituted by hydroxyl, pyrrolidonyl, phthalimidyl, alkoxy of 1 to 8 carbon atoms, allyloxy, benzyloxy, phenylethoxy, phenoxy, methylphenoxy, chlorophenoxy, methoxyphenoxy, or optionally substituted arylsulfonyl, or is benzyl, phenylethyl or cyclohexyl, or is phenyl which is unsubstituted or substituted by chlorine, bromine, nitro, methyl, ethyl, methoxy, ethoxy, phenoxy or dialkylamino (where alkyl is of 1 to 4 carbon atoms), or is naphthyl, pyridyl, thienyl or furyl, the substituents B1 independently of one another are hydrogen or an aliphatic, cycloaliphatic, araliphatic, aromatic, heterocyclic or acyl radical and B2 is hydrogen or an aliphatic radical. The dyes may be used for dyeing synthetic fibers, especially polyesters, and cellulose/polyester union fabrics, and give very fast dyeings.
