AB - Homopolymer of 2‐methyl‐N‐vinylimidazole and copolymer of the monomer with acrylamide were coupled with some aromatic diazonium compounds to give polymeric azo dyes. The dyestuff prepared from the homopolymer was soluble in water only when it was coupled with diazonium component containing sulfonic acid group, but the dyestuffs prepared from the copolymer were soluble. The reactivity, chemical structure, color, and dyeability of the polymeric dyes are discussed by comparing them with those of the corresponding monomeric dyes. The color fastness of the polymeric dyes was found to be in a high class; the rubbing and dry‐cleaning fastness were especially excellent.
