摘要： There are described novel greenish-yellow cationic dyes of the formula ##STR1## wherein R.sub.1 is hydrogen, halogen, lower alkyl, lower alkoxy or NO.sub.2,R.sub.2 is unsubstituted lower alkyl, or lower alkyl which is substituted by: hydroxyl, lower alkoxy, halogen, CN, carboxylic acid amide, carboxylic acid alkyl ester or phenyl, or R.sub.2 is alkenyl (C.sub.3 -C.sub.4), theR.sub.3 's independently of one another are each lower alkyl, or both R.sub.3 's together form a carbocyclic 5-, 6- or 7-membered ring,R.sub.4 is hydrogen, lower alkyl, unsubstituted aryl or substituted aryl,R.sub.5, R.sub.6 and R.sub.7 independently of one another are hydrogen, lower alkyl, lower alkoxy, halogen, NO.sub.2, CN or lower alkylsulfonyl, andA is an anion;processes for producing them, and their use for dyeing and printing textile materials, particularly polyacrylonitrile materials.

摘要： 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.sub.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, andT represents an anion, and the ringsA 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.
