Abstract (en)
[origin: EP0305839A2] A process for the discontinuous dyeing of cellulosic fibres is carried out in the presence of amines containing glycol ether groups and of the formula <IMAGE> in which R represents C12-C22-alkyl, cycloalkyl, aryl or aralkyl each having 12 to 22 C atoms R1 represents hydrogen, C1-C4-alkyl, benzyl or <IMAGE> R2 represents hydrogen or methyl, R3 represents <IMAGE> R4 represents arylene having 6 to 18 C atoms or C1-C17-alkylene, x, y and z represent an integer of from 1 to 20 and the sum x + y + z should be 5 to 20, X<(-)> represents an anion, with the proviso that at least 80% of the alkylene oxide units contained in the molecule are ethylene oxide units.
