Abstract
Fibres, films and other shaped articles of polymers or copolymers of acrylonitrile are dyed or printed with an aminoanthraquinone carboxylic acid amide the amido nitrogen atom of which is substituted by a radical containing at least one tertiary amino group. The tertiary amino group may be joined to the amido nitrogen atom via alkylene, cycloalkylene, arylene or aralkylene radicals and its remaining linkages may be substituted by identical or different and, if desired, substituted alkyl, aryl or aralkyl groups, or alternatively its remaining linkages together with the nitrogen atom may belong to a heterocyclic ring system, e.g. a morpholino-, pyrrolidino- or piperidino group. The anthraquinone nucleus may contain other substituents, e.g. halogen atoms or nitro, alkoxy, aryloxy or substituted amino groups. Dyeing is preferably effected in an acid bath at the boil, with the addition of dispersing agents and electrolytes such as sodium sulphate or acetate. Numerous examples are given.
