    • Reactive dyestuffs are disclosed having the formula ##STR1## in which D is the radical of an organic nonanthraquinoid dyestuff; R is hydrogen or a lower alkyl; R.sub.1 is amino or substrated amino with substituents attached by a single bond, optionally etherified hydroxy, optionally etherified mercapto or an optionally substituted hydrocarbon radical; Q is an alkylene, aralkylene, arylene, --CO-- or --SO-- which is directly linked to a carbon atom of the ring of the dyestuff D; n is the number 0 or 1 and F is a fluoro substituent. The group --N(R) is directly linked to a carbon atom of the triazine ring and on the other side, the group --N(R) is linked to a carbon atom of the ring of the dyestuff D either directly (if n = 0) or (if n = 1) via one of the bridge members mentioned above. These dyestuffs are primarily suitable for dyeing of textile materials containing hydroxyl or nitrogen such as natural and regenerated cellulose, wood silk, polyamide and polyurethane. The fastness properties, particularly wet fastness, are excellent.
    • 公开了具有式“IMAGE”的反应性染料,其中D是有机非蒽醌染料的基团; R是氢或低级烷基; R1是具有通过单键连接的取代基的氨基或亚基氨基,任选醚化的羟基,任选醚化的巯基或任选取代的烃基; Q是与染料D的环的碳原子直接连接的亚烷基,亚芳基,亚芳基,-CO-或-SO-; n为0或1,F为氟取代基。 基团-N(R)直接连接到三嗪环的碳原子上,另一方面,基团-N(R)直接连接到染料D的环的碳原子上(如果n = 0)或(如果n = 1)。 这些染料主要适用于染色含有羟基或氮的纺织材料,如天然纤维素和再生纤维素,木丝,聚酰胺和聚氨酯。 坚牢度,特别是耐湿牢度优异。
