Sulfophenylamino containing tetrareactive triazine disazo dyestuffs and dyestuff compositions thereof

Abstract

Tetrareactive disazo dyestuffs of the formula ##STR1## wherein D represents a benzene radical containing at least one sulpho group; K represents a radical of 1-amino(or aminobenzoylamino)-8-naphthol-3,6-disulphonic acid, of 1-amino(or aminobenzoylamino)-8-naphthol-4,6-disulphonic acid, of 2-amino(or aminobenzoylamino)-5-naphthol-7-sulphonic acid, of 2-amino(or aminobenzoylamino)-8-naphthol-6-sulphonic acid, of 2-amino(or aminobenzoylamino)-5-naphthol-1,7-disulphonic acid, or of 2-amino(or aminobenzoylamino)-8-naphthol-3,6-disulphonic acid; B represents an aliphatic or aromatic radical; R.sub.1, R.sub.2 and R.sub.3 each independently represent hydrogen or alkyl having 1 to 6 carbon atoms; X represents chlorine, bromine or fluorine; and Y represents hydrogen, low-molecular alkyl or alkoxy, acetylamino, halogen, carboxy or sulpho; said dyestuffs being useful in dyeing materials such as silk, leather, wool, superpolyamide fibers, superpolyurethanes and fibrous cellulose containing materials, the dyeings being characterized by high depth of color and good fastness to light and wet processing, such as washing.
