They have fiber-reactive properties and are used for preparing strong and fast dyeings on hydroxy- and/or carboxamido-containing material, preferably fiber material, such as synthetic polyamide, wool and in particular cellulose fibers. ##STR1## where: M is hydrogen or a salt-forming metal,K.sup.o is a radical of the formula (2A) or (2B) ##STR2## where Z is a radical of the formula (3) ##STR3## where R.sup.o is hydrogen or lower alkyl which may be substituted by certain substituents, G is halogen, methoxy, hydroxy or substituted or unsubstituted anilino, Z.sup.1 is a radical of the formula (3a) or (3b) ##STR4##--alk--SO.sub.2 --Yand wherein A, B, R*, R", Y, a, k, D, E and K are as defined in the specification.
Abstract:
New dyestuff mixtures contain in each case at least one fluoropyrimidine dyestuff of the general formula (I) ##STR1## and a vinylsulfonyl dyestuff of the formula (II) ##STR2## in which the substituents have the meaning given in the description.
Abstract:
Reactive azo dyestuffs of the formula ##STR1## wherein R, Z and A have the meaning indicated in the description, and their use for dyeing and printing materials containing hydroxyl groups or amide groups, such as textile fibers, filaments and fabrics of wool, silk and synthetic polyamide fibers and polyurethane fibers, and for dyeing and printing natural or regenerated cellulose in shades which are fast to washing.
Abstract:
Water-soluble azo compounds corresponding to the general formula D--N.dbd.N--K which have advantageous fiber-reactive dyestuff properties and dye materials containing carboxamide groups and in particular materials containing hydroxy groups, such as wool and in particular cellulose fiber materials, in deep fast shades are described.In the formula D--N.dbd.N--K:D is a radical of the general formula ##STR1## in which Y is the vinyl group or an ethyl group in the .beta.-position which can be removed by an alkaline radical, R is hydrogen, nitro, lower alkyl, lower alkoxy, carboxy or hydroxy or halogen, M is hydrogen or a salt-forming metal atom and n is the number zero or 1; andK is a radical of a water-soluble coupling component which can be coupled in one position and can also contain an azo group, or the radical of a water-soluble coupling component which can be coupled in two positions, in each case from the series comprising aminobenzenes, phenols, naphthols, aminonaphthols, acylamino-napthols, dihydroxynaphthalenesulfonic acids, phenylazo-aminonaphtholsulfonic acids, naphthylazo-aminoaphtholsulfonic acids, 5-pyrazolones, 5-aminopyrazoles, acetoacetyl arylides, 2-hydroxy-6-pyridones and hydroxyquinolines, it also being possible for K to contain one or more fiber-reactive groups, in addition to the substituents customary in dyestuffs.Precursors of these azo compounds of the general formula ##STR2## in which G is the amino or nitro group, R, M and n have the abovementioned meanings and Y' is the .beta.-hyroxyethyl group or has one of the abovementioned meanings for Y are furthermore described.
