Water soluble azo dyes containing a cyanoamino-triazinyl-amino group and

Azo compounds which contain a 1-sulfo-6-carboxy-2-aminonaphthalene diazo

Phthalocyanine dyes, in particular copper phthalocyanine and nickel phthalocyanine dyes which contain one or more groups of the formula given and defined below ##STR1## or one or more carboxy groups or both groups and which furthermore can contain one or more sulfo groups, customary sulfonamide groups and/or groups of the formula given and defined below ##STR2## dye hydroxy- and/or carboxamide-containing materials, in particular fiber materials, such as cellulose fiber materials, wool and polyamide fibers, in fast, predominantly green hues of high color strength. In the formulae: R is hydrogen or a lower substituted or unsubstituted aliphatic radical, A is an aromatic carbocyclic or aromatic heterocyclic radical or an alkylene radical, which may be interrupted by 1 or 2 hetero groups, X is a direct bond or a divalent organic bridging member or together with the group --N(R)-- forms the divalent radical of a saturated heterocycle containing two N atoms, Y, in the case where A is an aromatic radical, is a direct bond or a carbamoylalkylene group or a methylene, ethylene, methylamino or .beta.-cyanoethylamino group, or Y is lower alkylene, in which case the grouping --X--A-- must be a direct bond and m is 2, Z is a fiber-reactive group of the vinylsulfonyl series and m is the number 1 or 2.

Disazo compounds containing a cyanoamidotriazinyl radical as a bridging

Monoazo reactive dye which contains a dicyanoaminotriazinyl group and a

Fiber-reactive dyes which contain a ureidoalkylene group

Water-soluble phthalocyanine dyestuffs, processes for their preparation and their use Phthalocyanine dyestuffs, in particular copper phthalocyanine and nickel phthalocyanine dyestuffs, which contain one or more groups of the formula define below ##STR1## or one or more carboxy groups, or both groups, and which furthermore can have one or more sulfo groups, customary sulfonamide groups and/or groups of the general formula defined below ##STR2## dye materials containing hydroxy and/or carboxamide groups, in particular fiber materials, such as, for example, cellulose fiber materials, wool and polyamide fibers, in deep-colored, fast, mainly green shades. In the formulae:

Water-soluble phthalocyanine dyestuffs, processes for their preparation

Water-soluble fiber-reactive dyestuffs containing a

Anthraquinone, phthalocyanine, formazan, azomethine, dioxazine, phenazine, triphenylmethane, xanthene, thioxanthone, nitroaryl, naphthoquinone, pyrenequinone and perylenetetracarbimide dyes which contain one or two groups of the general formula ##STR1## where Y is vinyl or an ethyl group which contains in a .beta.-position a substituent which is eliminable by means of alkali to form a vinyl group, and W is a direct bond or a group of the general formula ##STR2## where M is a hydrogen atom or an alkali metal and n is zero, 1 or 2. The dyes have very good fiber-reactive properties and are advantageously suitable for dyeing carboxamino- and/or hydroxy-containing material, for example wool, in particular cellulose fiber materials; on these materials they produce strong fast shades in a high degree of fixation.

Water-soluble fiber-reactive dyes and preparation and use thereof

Water-soluble fiber-reactive dyes which contain one or more groups of the general formula (1) ##STR1## where R.sup..alpha. and R.sup..beta. are each hydrogen or lower alkyl,

Water-soluble fiber-reactive dyes, containing an amino-substituted

Water-soluble triphendioxazine compounds of the formula (1) with quaternary ammonium groups ##STR1## in which the substituents are defined in claim 1. The compounds (1) have fiber-reactive dyestuff properties and dye, for example, cellulose fiber materials, wool and synthetic polyamide in deep, fast shades.

Water-soluble triphendioxazine compounds and precursors thereof

Water-soluble disazo compounds, processes for their preparation of their use as dyestuffs Disazo compounds of the general formula (1) defined below, ##STR1## which have fiber-reactive properties and are suitable as useful dyestuffs for dyeing material containing carboxamide groups and/or material containing hydroxy groups, such as fiber material, for example wool and cellulose fiber materials, are described. In formulas (1):

Water-soluble disazo compounds, having a fiber-reactive group of the

Water-soluble monoazo compounds having fiber-reactive dyestuff properties which correspond to the general formula ##STR1## in which M is a hydrogen atom or an alkali metal,

Water-soluble azo compounds having a 6-carboxy-2-naphthal as coupling

Compounds according to the general formula ##STR1## in which: D is phenyl, optionally substituted by sulfo, carboxy, alkyl, alkoxy, alkanoylamino and/or chlorine, at least by sulfo or carboxy, or is a sulfosubstituted naphthyl;

Water-soluble disazo compounds, containing a vinylsulfonyl or
