A dye of the formula ##STR1## wherein R.sup.1 is is fluorine, chlorine, bromine, methyl, ethyl, cyano, carboxyl, nitro, tribfluoromethyl, methylsulfonyl, phenylsulfonyl, acetyl, C.sub.1 -C.sub.4 alkoxy, phenoxy, chlorophenoxy or benzoyl; R.sup.2 is hydrogen, chlorine, bromine, methyl, ethyl, C.sub.1 -C.sub.4 alkoxy, benzthiazol-2-yl, 6-methylbenzthiazol-2-yl, acetylamino, carboxyl aminosulfonyl, or aminocarbonyl; R.sup.3 is hydrogen chlorine, bromine or methyl; R.sup.5 is hydrogen, methyl, methoxy or ethoxy; and X is fluorohydroxyphosphonyl or dihydroxyphosphonyl. The dye of the present invention is useful in the dyeing of cellulose-containing material, polyamides and leather. The high tinctorial strength of the dyes and the very good lightfastness and wetfastness properties of the dyeings are particularly noteworthy.

Reactive pyrazole group containing monoazo dye

Reactive dyes which in the form of the free acids correspond to the general formula ##STR1## where A is fluorine, chlorine or bromine,

Reactive bis-triazinyl stilbene dyes

Reactive dyes which in the form of the free acids correspond to the general formula ##STR1## where R.sup.1 is hydrogen, chlorine, bromine, methyl or hydroxysulfonyl, R.sup.2 is chlorine, bromine or phenyl, or is C.sub.1 -C.sub.4 -alkoxy which is unsubstituted or substituted by hydroxyl, C.sub.1 -C.sub.4 -alkoxy or phenoxy, or is phenoxy or naphthoxy which are unsubstituted or substituted by C.sub.1 -C.sub.10 -alkyl and X is fluorine, chlorine or bromine, are exceptionally suitable for dyeing hydroxyl-containing material, e.g. cellulose or leather.

Triazinyl reactive dyes containing a 1-naphtol-4,8-disulfonic acid

Uniformly dyed water-swellable cellulosic fibers obtained by dyeing cellulosic fibers, in the swollen state, with a dye of the formula ##STR1## where X is hydrogen, chlorine, bromine, cyano, nitro, alkylsulfonyl of 1 to 4 carbon atoms, phenylsulfonyl, methoxy or ethoxy, Y is hydrogen, chlorine, bromine, cyano or nitro, Z is a radical of the formula ##STR2## Q is oxygen or sulfur, R.sup.1 is alkyl of 1 to 4 carbon atoms, methoxymethyl, phenoxymethyl or phenyl which is unsubstituted or substituted by chlorine, bromine, nitro, methyl, methoxy or ethoxy, R.sup.2 is hydrogen, methyl, ethyl, phenyl or phenyl substituted by chlorine, bromine or methyl, R.sup.3 is hydrogen, methyl or, if R.sup.2 is methyl, is C.sub.1 to C.sub.4 alkoxycarbonyl, R.sup.2 and R.sup.3 together with the linking carbon atoms are phenylene or phenylene substituted by chlorine, methyl, methoxy or ethoxy and K is a radical of a coupling component selected from the pyrazolone, pyrazole, indole, quinolone or homophthalimide series.
