Abstract: Disazo dyes of formula (I) are new. (n (I), X1 is Cl, Br, Me, Et, OMe, OEt, MeSO2, EtSO2, substd. carbamoyl or sulphamoyl, or a carboxylic ester gp.; X2 is H, Cl, Br, Me, OMe, NO2 or CN; Z is H, Me, Et, OMe, OEt, Cl or Br; R1 and R2 are H or opt. substd. alkyl, or NR1R2 is pyrrolidino, piperidino, morpholino or hexamethylenimino, provided that NR1R2 is in the 5 or 8 posn. of the quinoline ring. (I) are esp. useful for dyeing or printing cellulosic fibres, including cotton and polyester-cotton blends, e.g. using the process of DE1811796. They give blue to black shades with good fastness to light, solvents and abrasion.

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: A compound having the formula: I where X is hydrogen, chlorine or bromine, B is hydrogen, methyl, ethyl or propyl, and one of the radicals R1 or R2 is phenyl which is unsubtituted or mono- or poly-substituted by chlorine, methyl, ethyl, t-butyl, phenoxy, methoxy, ethoxy, propoxy or butoxy, and the other is C2-C8-alkyl which is unsubstituted or substituted by C1-C8-alkoxy or phenyl, or is allyl, cyclopentyl, cyclohexyl, methylcyclohexyl, The compounds of formula (I) are used as dyes, preferably for cellulose and cellulose-containing fabrics.
