Abstract
Abstract N,N-Dialkyl-N-aminoalkyl-N-aminophenylalkyl quaternary ammonium salts and N-methyl-N-(3-aminophenoxy-2-hydroxy-1-propyl)-N,N-bis(3-aminopropyl) quaternary ammonium salts and their N-nitrophenylalkyl and N-(3-nitrophenoxy) precussor quaternary ammonium salts, respectively are intermediates to water-soluble azo-dyestuffs useful for coloring natural fibers, synthetic fiber-forming materials and cellulosic materials. These dyes dye cotton and paper various shades of yellows, reds, and oranges with less prone to bleed and with a high degree of discharge when bleached with hypochlorite or chlorine bleaches.
