Abstract
Abstract There are described new cationic dyes of the formula ##STR1## wherein R 's independently of one another each represent a straight-chain or branched-chain alkyl group having 1 to 4 carbon atoms, X represents CH or N, R 1 represents hydrogen in the case where X=CH, or represents a straight-chain or branched-chain alkyl group having 1 to 6 carbon atoms in the case where X=N, Z represents unsubstituted or substituted alkylene which has 2 to 4 carbon atoms and which can be interrupted by one or more hetero atoms, n represents 0 or 1, and T represents an anion, and the rings A and/or B can optionally contain further substituents, processes for producing these dyes, and their use for dyeing and printing materials dyeable with cationic dyes, for dope dyeing textile materials consisting of homo- or copolymers of acrylonitrile, and for dyeing wet tow, by which means are obtained yellow dyeings having good fastness properties.
