| titleOfInvention | Water-soluble quaternary ammonium non-heterocyclic azo dyestuffs |
| abstract | Water-soluble cationic dyestuffs of the formulae ##STR1## WHEREIN R 0 is hydrogen, lower-alkyl or hydroxy-lower-alkyl; n R 1 is lower-alkyl, lower-alkenyl or hydroxy-lower-alkyl; n R 2 is lower-alkyl, lower-alkenyl, hydroxy-lower-alkyl or -(lower-alkylene)-NR 0 Y or R 1 and R 2 together with the nitrogen atom, are pyrrolidino, piperidino or 4-lower-alkanoyl piperazino; n Y is hydrogen or ##STR2## wherein R is hydrogen, lower-alkyl, lower-alkenyl, phenyl or phenyl-lower-alkyl; n 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. n k is a small integer whose value is dependent on the nature or A such that it has a range from one to two; n R 8 is lower-alkyl, lower-alkenyl or hydroxy-lower-alkyl; n R 9 is lower-alkyl, hydroxy-lower-alkyl or NH 2 ; n R 10 is lower-alkyl or lower-alkenyl; n A 1 is an aromatic azo dyestuff residue attached to the quaternary ammonium nitrogen atom through a lower-alkylene bridge; n g is a small integer whose value is dependent on the nature of A 1 such that it has a range from one to two; n R 8' is lower-alkyl; n R 9' is lower-alkyl, lower-alkenyl or hydroxy-lower-alkyl; n R 10' is lower-alkyl, lower-alkenyl or hydroxy-lower-alkyl or R 9' and R 10' together with the nitrogen atom are morpholino; n A 2 is an aromatic azo dyestuff residue attached to the quaternary ammonium nitrogen atom through a lower-alkylene bridge; n h is a small integer whose value is dependent on the nature of A 2 such that it has a range from one to two; and n An is an anion n Are particularly useful for coloring natural fibers, synthetic fiber-forming materials and cellulosic materials. These dyes dye cotton and paper various shades of stable yellows, reds and oranges. The dyeing from these dyes on paper are less prone to bleed and have a high degree of color discharge when bleached with hypochlorite or chlorine bleaches. |
