    Abstract: Compounds of the general formula I I where B2 and B2 independently of one another are hydrogen, C1-C6-alkyl which may or may not be interrupted by oxygen or sulfur and is unsubstituted by hydroxyl, C1-C4-alkoxy, C1-C4-alkylmercapto, cyano, phenylmercapto (which is unsubstituted by chorine or methyl), unsubstituted or substituted carbamoyl or a carboxylic acid ester group, benzyl or phenylethyl which are unsubstituted or substituted in the ring by chlorine, bromine, methyl, ethyl, methoxy or ethoxy, phenyl which is unsubstituted or substituted by chlorine, bromine, hydroxyl, methoxy, ethoxy, methyl, C1-C4-alkylmercapto, C1-C4-alkanoylamino or amino, unsubstituted or substituted carbamoyl or a carboxylic acid ester group, B2 may in addition be cyano, C2-C4-alkanoyl, benzoyl which is unsubstituted or substituted by chlorine, methyl, methoxy or ethoxy, C1-C6-alkylsulfonyl, or phenylsulfonyl, which is unsubstituted or substituted by chlorine, bromine, methyl, methoxy, ethoxy, amino, C1-C4-alkanoylamino, C1-C4-alkylsulfonyl or benzoylamino, B1 and B2 together may also be a saturated 5-membered or 6-membered ring which may or may not contain oxygen or sulfur, X is oxygen or imino and the ring A may be substituted. Such compounds are outstandingly suitable for dyeing synthetic fibers and plastics.
