A water-soluble basic dyestuff which corresponds to the formula (A-Q.sup.+) X.sup.-, in which A represents the radical of a monoazo- or disazo dyestuff which may contain no other substituents than lower alkyl, trifluoromethyl, lower alkoxy, chlorine, bromine, cyano, nitro, phenylazo, lower alkoxycarbonyl, lower alkanecarbonyl, lower alkanesulfonyl, acylamino and sulfonic acid amide, or the radical of an amino- or hydroxyanthraquinone dyestuff which may contain no other substituents than lower alkyl, lower alkoxy, chlorine, bromine, cyano, nitro, lower alkoxycarbonyl, lower alkanecarbonyl, lower alkanesulfonyl, acylamino and sulfonic acid amide, or the radical of a styryl dyestuff which may contain no other substituents than lower alkyl, lower alkoxy, cyano and lower alkoxy carbonyl or the radical of a nitro dyestuff which may contain no other substituents than lower alkyl, lower alkoxy, chlorine, bromine, cyano, nitro, lower alkoxycarbonyl, lower alkanecarbonyl, lower alkanesulfonyl and sulfonic acid amide, Q represents a quaternated hydrazide group of the formula ##EQU1## wherein R.sub.1 represents lower alkyl or hydrogen, R.sub.2, R.sub.3 and R.sub.4 each represents lower alkyl and X represents an anion, and in which formula one of the symbols R.sub.2, R.sub.3 and R.sub.4 may represent a benzyl or a phenyl residue, and wherein "aryl" means unsubstituted phenyl or phenyl substituted by lower alkyl, lower alkoxy, chlorine or bromine and "lower" means containing up to 4 carbon atoms. They are valuable dyestuffs yielding on synthetic fibres dyeable by cationic dyestuffs, especially polyacrylonitrile fibres dyeings of good general fastnesses.
