1,4-Diaminoanthraquinone derivatives containing a halopyrimidinyl or haloquinoxaline-6-carbonyl reactive group are useful as reactive dyestuffs for the dyeing or printing of leather and textile materials.
摘要:
Disclosed are anthraquinone dyestuffs which, in free acid form, are of formula I, ##STR1## in which R signifies an alkyl radical of 6 to 24 carbon atoms, an unsubstituted cyclohexyl radical or a cyclohexyl radical substituted by one or more substituents selected from halogen atoms and alkyl and alkoxy radicals,R.sub.1 and R.sub.2, independently, each signifies an alkyl radical of 1 to 6 carbon atoms,X signifies --O-- or a direct bond,ring A is unsubstituted or substituted by one or two halogen atoms, hydroxyl groups or C.sub.1-4 alkyl or alkoxy groups,their production and use in the dyeing of anionic dyeable substrates, particularly natural and synthetic polyamide fibers.
摘要:
Water-soluble anthraquinone dyes which bear one or two 3,5,5-trimethylcyclohexylamino groups in the 1- and/or 4-positions and one or two -SO.sub.3 H groups bound either directly to a carbon atom of an aromatic ring or indirectly over an oxygen atom to a carbon atom of an aliphatic chain.
