    Abstract: Basic azo dyes useful for dyeing or printing polymeric material have the formula (* CHEMICAL STRUCTURE *) where R1 is hydrogen, C1-C4-alkyl, C1-C4-alkoxy or C1-C4-alkanoylamino, R2 is hydrogen, C1-C4-alkyl, C1-C4-alkoxy or a radical of the formula CO-X, and X is hydroxyl, C1-C4-alkoxy, amino, mono- or di(C1-C6-alkyl)amino or a radical of the formula (* CHEMICAL STRUCTURE *) (* CHEMICAL STRUCTURE *) (* CHEMICAL STRUCTURE *) where n is 0 or 1, R3, R4 and R5 are hydrogen or substituted or unsubstituted C1-C4-alkyl, R6 is hydrogen or C1-C4-alkyl, L is C2-C6-alkylene, and An(negative earth) is one equivalent of an anion, with the proviso that at least one basic or quaternary radical is present in the molecule.
