Water-soluble halotriazine-containing axo compounds, preparation thereof and use thereof as dyes

Described are fiber-reactive, water-soluble monoazo compounds conforming to the hereinbelow indicated and defined general formula (1) that are capable of dyeing hydroxyl- and/or carboxamido-containing material, especially fiber material, such as cellulose fibers, for example cotton, or regenerated cellulose fibers and also wool and synthetic polyamide fibers in red shades and in high color strength and good fastnesses. where M is hydrogen or an alkali metal, m is 1, 2 or 3, X is chlorine or fluorine, R0 is hydrogen or carboxyl, R is alkyl of 1 to 4 carbon atoms which is unsubstituted or substituted by hydroxyl, carboxyl, sulfo, sulfato, phosphate, chlorine, alkanoyloxy of 2 to 5 carbon atoms or alkoxy of 1 to 4 carbon atoms, and R is hydrogen, alkyl of 1 to 4 carbon atoms, which may be substituted, alkoxy of 1 to 4 carbon atoms, which may be substituted, alkanoylamino of 2 to 5 carbon atoms, optionally substituted benzoylamino or halogen, and R2 is hydrogen, carboxyl or sulfo and the -SO3M group in the aminonaphthol radical is disposed meta or para relative to the amino group.
