Material Applications of Novel Disperse and Mordent Azo Dyes Based on 2-Hydroxy-4-methoxybenzophenone

Abstract

Novels disperse and mordent azo dyes were prepared by coupling of various diazo solutions of aromatic amines with 2-hydroxy-4-methoxybenzophenone. The resultant dyes were characterized by elemental analyses, IR and ¹H NMR spectral studies. The UV-visible spectral data have also been discussed in terms of structural property relationship. The dyeing performance of all the dyes was evaluated on wool and polyester textile fibers. The dyeing of chrome pretreated wool and polyesters have also been monitored. The results show that better hue was obtained on mordented fiber. Results of bactericidal studies of chrome pretreated fibers revealed that the toxicity of mordented dyes against bacteria is fairly good. Some of the dyes have also been used for pigmentation as well as photo stabilization of polymethyl methacrylate sheet.
