Abstract
Abstract A dye of the formula ##STR1## wherein R 1 is is fluorine, chlorine, bromine, methyl, ethyl, cyano, carboxyl, nitro, tribfluoromethyl, methylsulfonyl, phenylsulfonyl, acetyl, C 1 -C 4 alkoxy, phenoxy, chlorophenoxy or benzoyl; R 2 is hydrogen, chlorine, bromine, methyl, ethyl, C 1 -C 4 alkoxy, benzthiazol-2-yl, 6-methylbenzthiazol-2-yl, acetylamino, carboxyl aminosulfonyl, or aminocarbonyl; R 3 is hydrogen chlorine, bromine or methyl; R 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.
