摘要：The invention relates to a process for spin dyeing polymers of acrylonitrile or copolymers containing predominantly acrylonitrile, which process comprises adding to the spinning solution a monocationic dye salt of the formula <IMAGE> wherein D is the group of atoms necessary to close a 5-membered heterocyclic ring containing two N-atoms, or to close a 6-membered heterocyclic ring, which rings may optionally contain fused benzene rings, or is the group of atoms necessary to close a benzthiazole ring, and Q is the radical of a carbocyclic or heterocyclic aromatic coupling component, and R1 is alkyl, aralkyl or aryl. The yellowish-red transparent fibres obtained have excellent fastness properties.
