Patent number: 4544738
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.
