Abstract
Cationic dyestuffs of the formula ##STR1## in which R, R' and R" denote alkyl, alkenyl, cycloalkyl or aralkyl and R.sub.1 denotes hydrogen, alkyl, alkenyl, cycloalkyl or aralkyl or R.sub.1 can form a five-membered or six-membered heterocyclic ring with the ring B, R.sub.2 denotes an alkylene group of which the chain can be interrupted by 0, Y denotes a --CO-- or --O--CO--O-- group, A denotes an aromatic ring and X.sup.- denotes an anion, and n, n' and n" independently of one another are 0 or 1, with the proviso that the sum n + n' + n" is 2, Are suitable for dyeing and printing of natural and synthetic materials with good fastness properties with respect to light, wet processing, rubbing, decatizing, sublimation and perspiration.
