Zusammenfassung:	Disclosed are anthraquinone dyestuffs which, in free acid form, are of formula I, I 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, R1 and R2, 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 C1-4alkyl or alkoxy groups, their production and use in the dyeing of anionic dyeable substrates, particularly natural and synthetic polyamide fibers.
