Abstract: A process for the preparation of dyes of the formula ##STR1## in which D is a dye radical and R.sub.1 and R.sub.2 independently of one another is hydrogen or C.sub.1-4 -alkyl, which comprises reacting cyanuric fluoride of the formula ##STR2## simultaneously with a dye of the formula ##STR3## and with an ammonium salt of an amine of the formulaH.sub.2 N--R.sub.2 (4)in a neutral to alkaline medium, to give dyes of the formula (1) as single compounds in good yields in one operation. The novel process has the advantage of being able to be carried out as a "one-pot process" in a closed reaction vessel so that the apparatus is simple and immission by cyanuric fluoride is excluded.

Abstract: A process for producing granulates of water-soluble dyes by means of fluidized bed granulation, wherein there is added a granulating auxiliary having a softening point or softening range between 30.degree. and 150.degree. C. and consisting of(a) at least one compound of the formula IA--(CH.sub.2 CH.sub.2 O).sub.n --H (I)in which A is the group R--O-- or ##STR1## wherein R is an aliphatic or alicyclic hydrocarbon radical having 8 to 22 carbon atoms, R' is an aliphatic hydrocarbon radical having 8 to 22 carbon atoms, and n is 10 to 200, preferably 20 to 150, or(b) a mixture of a compound of the formula II ##STR2## in which m is 50 to 500, and x is 3 to 5, with a compound of the formula IIIR.sub.1 --NH--CO--NH--R.sub.1 (III),in which each R.sub.1 independently of the other is hydrogen or methyl, or(c) a mixture of a compound of the formula I with at least one compound of the formula II or III.

Abstract: The invention provides reactive dyestuffs of the formula ##STR1## wherein X is a fibre-reactive group of the triazine or pyrimidine series; R.sub.3 and R.sub.4 are each hydrogen; n is 0 or 1; and k is a pyridone or pyrimidone coupling component; the dyestuffs are particularly suitable for dyeing and printing natural and regenerated cellulose fibre materials and synthetic polyamide fibre materials.

Abstract: 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.
