Abstract

There are described novel greenish-yellow cationic dyes of the formula < IMAGE > wherein R1 is hydrogen, halogen, lower alkyl, lower alkoxy or NO2, R2 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 R2 is alkenyl (C3-C4), the R3's independently of one another are each lower alkyl, or both R3's together form a carbocyclic 5-, 6- or 7-membered ring, R4 is hydrogen, lower alkyl, unsubstituted aryl or substituted aryl, R5, R6 and R7 independently of one another are hydrogen, lower alkyl, lower alkoxy, halogen, NO2, CN or lower alkylsulfonyl, and A is an anion processes for producing them, and their use for dyeing and printing textile materials, particularly polyacrylonitrile materials.
