    摘要: A process for the elimination of the fluorescence effect resulting from the treatment of fibrous materials with optical anionic agents is described which consists of treating the fibrous materials with a water soluble salt of a polymer containing the imidazoline ring of formula I ##STR1## wherein X is in the position meta or para with respect to the imidazoline ring and X is ##STR2## or --CO--NH-- The imidazoline-containing compounds prepared by reacting diethylenetriamine or triethylenetetramine with terephthalic or isophthalic acid followed by cyclization are reacted with dicyandiamide. The water soluble salt is an acid addition salt or a quaternary ammonium salt. The new polymers are described.
