    Notes: Es wurden zwei neue Gruppen von Reaktivfarbstoffen entwickelt. Die eine Gruppe (Levafix®-Farbstoffe) umfaßt Verbindungen, die als Reaktivgruppen  - SO2NH—CH2—CH2—OSO3H oder —CH2—N(Alkyl)—CH2—CH2—OSO3H enthalten. Die Farbstoffe dieser Gruppe reagieren mit der Cellulosefaser unter Bildung von Celluloseäthern, z. B. R—SO2NH—CH2—CH2—O—Cellulose. Bei der im zweiten Teil beschriebenen Gruppe (LevafixE®-Farbstoffe) handelt es sich um Carbonsäureamide aus 2.3-Dichlorchinoxalin-6-carbonsäure und Farbkörpern, die primäre oder sekundäre Aminogruppen enthalten.

    Notes: Two new groups of reactive dyestuffs have been developed. One group (Levafix® dyes) comprises compounds which contain —SO2NH—CH2—CH2—OSO3H or —CH2—N(alkyl)-CH2—CH2—OSO3H as reactive groups. The dyes of this group react with cellulose fibers to form cellulose ethers, e.g. R—SO2NH—CH2—CH2—O—cellulose. The substances in the second group (Levafix-E® dyes) consist of the amides formed from 2,3-dichloroquinoxaline-6-carboxylic acid and dyestuffs containing primary or secondary amino groups.
