Notes:
The reaction of dihydroxyanthraquinone (DHA) and amines in the presence of catalyst has been reported. We found that DHA reacted easily with hexamethylenediamine in chloroform or toluene without addition of any catalyst, and mono-or dihexamethylenediamine-substituted anthraquinone, a violet green colourant, was formed. Using the colourant as a comonomer in the polycondensation of caprolactam or nylon-6,6 salt, coloured nylon-6 and nylon-6,6 fibres were prepared.
