Reactive dyes contng fluorotriazine gps, for dyeing

摘要

Reactive dyes contng fluorotriazine gps, for dyeing n-contng fibre material such as wool, silk, superpolyamides and polyurethanes. B2A. Are produced by introducing into an organic non-anthraquinoid dye or intermediate at least one gp or formula in which Q = alkylene, aralkylene, arylene, -CO- or -SO2- gp, n = 0 or 1, R = H, 1-4C alkyl or hydroxyalkyl gp, R1 = amino gp which may contain substituents linked to the amino gp. by a single bond, an optionally etherified OH gp, optionally etherified thio gp or optionally substd hydrocarbon radical and the gp -(-Q-)n-Nr is directly linked to a C atom of an aromatic carbocyclic ring of the dye or intermediate . If an intermediate is used, this must be converted, in known manner, into the desired non-anthraquinoid reactive dye.
