Abstract: A process for dyeing cellulose-containing textile material, wherein a dye of the general formula I I where R is an aliphatic, cycloaliphatic, araliphatic or aromatic radical and n is 0 or 1, and where the rings A, B and C may be substituted and may carry a fused ring, is used. On cotton and especially on cotton/polyester union fabrics, the process according to the invention gives very fast, especially very lightfast, dyeings.

Abstract: The novel dyes are of formula (I) in one of the possible tautomeric forms: (where D is the residue of an aromatic or heterocyclic diazo component; X is CN or carbamoyl; R1 is opt. substd. alkyl, cycloalkyl or aralkyl; R2 is H or opt. substd. alkyl, cycloalkyl, aralkyl or aryl; m and n are 1 or 2; Circle- is an anion; the dyestuff molecule contains n quat. N atoms). (I) are yellow-violet dyes for anionically modified fibres, esp. polyesters, polyamides and acrylonitrile polymers. The prefd. cpds. are esp. fast to light and wetting.

Abstract: Novel water-sol. azo dyes are of formula (I), in the free acid form or in the form of one of its possible tautomers: (where D is the residue of a diazo component; X is CN or carbamoyl; n is 1-4; R' is opt. substd. alkyl, cycloalkyl or aralkyl; R2 is H, or opt. substd. alkyl, cycloalkyl, aralkyl or aryl). (I) are used as yellow-violet dyes for natural and synthetic polyamides, e.g. wool, silk, nylon 6 and 66, bright, fast dyeing being obtained.

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: Azo dyes of the triaminopyridine series of the formula 1, in which the substituents have the meanings stated in Claim 1, are prepared by reaction of a diazo compound with a coupling component and subsequent sulphonation. The resulting dyes are yellow to violet and are suitable for dyeing natural and synthetic polyamides.
