摘要:
Water-soluble cationic dyestuffs of the formulae ##SPC1##WhereinR.sup.0 is hydrogen, lower-alkyl or hydroxy-lower-alkyl;R.sup.1 is lower-alkyl, lower-alkenyl or hydroxy-lower-alkyl;R.sup.2 is lower-alkyl, lower-alkenyl, hydroxy-lower-alkyl or -(lower-alkylene)-NRO Y or R.sup.1 and R.sup.2 together with the nitrogen atom, are pyrrolidino, piperidino or 4-lower-alkanoyl piperazino;Y is hydrogen or ##EQU1## wherein R is hydrogen, lower-alkyl, lower-alkenyl, phenyl or phenyl-lower-alkyl;A is a member selected from the group consisting of an aromatic azo dyestuff residue attached to the quaternary ammonium nitrogen atom through a lower-alkylene bridge.k is a small integer whose value is dependent on the nature or A such that it has a range from one to two;R.sup.8 is lower-alkyl, lower-alkenyl or hydroxy-lower-alkyl;R.sup.9 is lower-alkyl, hydroxy-lower-alkyl or NH.sub.2 ;R.sup.10 is lower-alkyl or lower-alkenyl;A.sup.1 is an aromatic azo dyestuff residue attached to the quaternary ammonium nitrogen atom through a lower-alkylene bridge;g is a small integer whose value is dependent on the nature of A.sup.1 such that it has a range from one to two;R.sup.8.sup.' is lower-alkyl;R.sup.9.sup.' is lower-alkyl, lower alkenyl or hydroxy-lower-alkyl;R.sup.10.sup.' is lower-alkyl, lower -alkenyl or hydroxy-lower-alkyl or R.sup.9.sup.' and R.sup.10.sup.' together with the nitrogen atom are morpholino;A.sup.2 is an aromatic azo dyestuff residue attached to the quaternary ammonium nitrogen atom through a lower-alkylene bridge;h is a small integer whose value is dependent on the nature of A.sup.2 such that it has a range from one to two; andAn is an anionAre particularly useful for coloring natural fibers, synthetic fiber-forming materials and cellulosic materials.
