摘要：
Reactive dyes have the formula (I), in which n equals 1 or 2; R1 stands for hydrogen or hydroxylsulfonyl; R2 stands for hydrogen or hydroxy; R3 stands for substituted C¿1?-C4-alkyl, C5-C7-cycloalkyl or substituted phenyl; R?4¿ stands for hydrogen or R?3 and R4¿ form a heterocyclic rest together with the nitrogen atom that interconnects them; and D stands for the rest of a diazo or tetrazo component with at least one anchor rest. Also disclosed is the use of said dyes for dyeing or printing organic substrates having hydroxy groups or nitrogen atoms, and new aminonaphthalenes.
