Reactive dyes of formula ##STR1## wherein Y is a radical of formula ##STR2## or

Reactive dyes, their preparation and the use thereof

Reactive dyes of formula ##STR1## wherein Y is a radical of formula ##STR2## Z is --NH.sub.2, an unsubstituted or a substituted aliphatic or aromatic amino group; A is an unsubstituted or a substituted aliphatic or aromatic bridging group, and X is .beta.-sulfatoethyl, .beta.-thiosulfatoethyl, .beta.-phosphatoethyl, .beta.-acyloxyethyl, .beta.-haloethyl or vinyl; the benzene rings I, II and III may contain further substituents in addition to 2 to 4 sulfo groups and, in the benzene ring II, to the radical --NH--Y; and the reactive dyes of formula (1) contain only a single fibre-reactive radical, are especially suitable for dyeing or printing cellulosic fibre materials by the methods customarily employed for reactive dyes, and give dyeings and prints of good fastness properties in high color yield.

Reactive dyes

The invention relates to a process for dyeing or printing textile fibre materials in stable shades with reactive dyes which produce grey or black dyeings or prints, which process comprises dyeing or printing textile fibre materials with a mixture of heavy metal-containing, water-soluble reactive dyes which produce grey or black dyeings or prints, each component of which mixture, under identical dyeing, printing and fixation conditions, produces dyeings or prints with a tinge different from the tinge of the dyeings or prints produced by the other component, and carrying out subsequent fixation.

Process for dyeing or printing textile fibre materials in stable black

There is described a novel process for producing 1,8-naphtholactam compounds of the formula I ##STR1## wherein the symbols R, A and B have the meanings defined in claim 1. This process comprises reacting a 1,8-naphtholactone compound of the formula II ##STR2## in an aqueous medium, with an amine of the formula III

Process for producing 1,8-naphtholactam compounds

The invention relates to reactive dyes of the formula ##STR1## wherein R.sub.1 is hydrogen or unsubstituted or substituted C.sub.1 -C.sub.4 alkyl or phenyl, R.sub.2 is hydrogen or unsubstituted or substituted C.sub.1 -C.sub.4 alkyl, R.sub.3 is hydrogen, cyano, carbamoyl or sulfomethyl, R.sub.4 and R.sub.5 are each independently hydrogen, C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy, halogen, carboxy or sulfo, X is fluorine, chlorine or bromine, and Z is an unsubstituted or substituted benzthiazolyl-(2)-phenyl radical, which are suitable for dyeing or printing cellulosic fibers and produce brilliant greenish yellow dyeings.

Reactive dyes, process for their preparation and use thereof

Azo dyes of the formula ##STR1## wherein D is benzene, naphthalene, benzoylaminobenzene, azobenzene or stilbene, which is unsubstituted or substituted by alkyl of 1 to 4 carbon atoms, alkoxy of 1 to 4 carbon atoms, phenoxy, alkanoylamino of 1 to 6 carbon atoms, benzoylamino, amino, alkylamino of 1 to 4 carbon atoms, phenylamino, alkoxycarbonyl of 1 to 5 carbon atoms, alkylcarbonyl of 1 to 5 carbon atoms, nitro, cyano, acetyl, carbamoyl, ureido, hydroxy, carboxy, halogen or sulfo, and which contains a dihalo-s-triazinylamino or a monohalo-s-triazinylamino radical substituted by an alkyl, aryl, alkylthio, arylthio, hydroxy, alkoxy, aryloxy, -NH.sub.2, alkylamino, arylamino or heterocyclic amino group, wherein the halo-s-triazinylamino radical is bonded directly or via methylene to a ring carbon of D, and the amino group, by which the halo-s-trazinyl radical is bonded to a carbon atom in D is optionally substituted at the nitrogen atom by C.sub.1-4 -alkyl or -sulfoalkyl, R is hydrogen or alkyl of 1 to 4 carbon atoms, and R.sub.1 and R.sub.2, independently of one another, have the same meaning as those substituents referred to above of monohalo-s-triazinyl radicals in D; or a heavy metal complex thereof, are especially suitable for dyeing cotton fabric according to the exhaustion dyeing method and produce dyeings which have good fastness properties.
