Abstract: Used of diazo dyestuff of formula (I) for transfer printing is new. In (I), R = Me, Et, Pr, Bu, beta-methoxyethyl, beta-chloroethyl or allyl; the rings A, B and C may be further substd. and one may carry and annelted ring. Pref. R = Me, Et, Pr or Allyl, A, B and C are opt. substd. and the ring opt carries an annelated benzene ring. Used for yellow-orange transfer printing of polyester, polyamide and cotton-polyester textiles, having good fastness to light and wetting.

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: New Monoazo dyes of 2,6-diaminopyridine series contg. CN gps., are of formula (I) In the formula, X is carbamoyl or sulphamoyl, opt. N-substd. with 1-2C alkyl or alkoxy, NO2, CN, F, CF3, Cl, Br, methyl- or ethyl-sulphonyl, phenyl sulphonyl, formyl, acetyl, benzoyl, acetylamino or benzoylamino, or is phenylazo substd. with SO3H, or is 1-6C alkyl sulphonyl, phenyl sulphonyl or benzoyl. Y is H, Cl, methyl, methoxy, ethoxy, acetylamino or propionyl-amino, or with X may form a condensed benzene ring opt. substd. with SO3H, or a gp. (II). Z is H, Cl, methyl, ethyl, methoxy, SO3H or COOH; n is 1 or 2; R is H or 1-3C alkyl; A is CN or carbamoyl; R1 is H or a (cyclo)aliphatic araliphatic, aromatic or heterocyclic gp.; R2 is H or an aliphatic gp.) Used for the dyeing or printing of polyesters, and of polyamides if SO3H gps. are present. Also for bulk colouring of plastics.

Abstract: Uniformly dyed water-swellable cellulosic fibers obtained by dyeing cellulosic fibers in the swollen state with a dye of the formula in which one R is R1, OR1, SR1 or the other R is R1 and R2 independently of one another are hydrogen or an aliphatic, cycloaliphatic, araliphatic or aromatic radical, may also be a saturated heterocyclic radical, and D is the radical of a diazo component. The dyed fibers exhibit very good fastness properties.

Abstract: Dye compsns. contains quinophthalone dispersion dyes of formula (I) (in which R is H or an opt. substd. alkyl, cycloalkyl, aralkyl or aryl gp.; Z is Cl or Br X is H or OH and; n = 0.3). (I) are used as dispersion dyes for dyeing or esp. printing of cellulosic fibres or their blends by special processes, in yellow shades. Excellent fastness, esp. to washing and light is obtd. There is no bleeding into white backgrounds during washing.

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.
