Abstract: Synthetic fibers containing anionic groups, e.g. polyacrylonitrile modified with sulfonic acid groups, are dyed by exhaustion in a dyebath comprising: A. hydrocarbon chloride solvent; B. 0.1 to 4% of water based on the solvent; C. a basic dyestuff soluble in hydrocarbon chloride solvent; and D. an organic nitrogen compound containing at least 12 carbon atoms, e.g. a fatty amine such as dodecylamine.
