    摘要: Reactive dyestuffs are disclosed having the formula ##STR1## in which D is the radical of an organic nonanthraquinoid dyestuff; R is hydrogen or lower alkyl; R.sub.1 is amino or substituted 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.

    摘要: In the saponification of 1-acetamino-anthraquinone to produce the corresponding 1-amino-anthraquinone, the improvement which comprises effecting the saponification with aqueous alkali such as a hydroxide, oxide or carbonate of an alkali metal or an oxide or hydroxide of an alkaline earth metal. The saponification is effected in water, which may contain an organic solvent such as alcohol.
