Abstract

Special quaternary ammonium salts of 2,4,6-tris-(.omega.-dialkylamino-alkyleneamino)-triazines and 2,4,6-tris-(.omega.-dialkylaminoalkoxy)-triazines and their use in dyeing anionic polyacrylonitrile fibers with basic dyes; these special derivatives of triazine are particularly effective retarders.
