Abstract:

Bis-azo acid dyes were prepared by the coupling of 4,4'-methylene bis(anthranilic acid) with various pyrazolone coupling components. The resultant dyes were characterized by elemental analyses, IR and NMR spectral studies. The UV-visible spectral data have also been discussed in terms of structural property relationship. The dyeing assessment of all the dyes was evaluated on wool and nylon textile fibres. The results show that a better hue was obtained on wool and nylon fibers. The results of the anti-bacterial properties of the bis-azo acid dyes revealed that the toxicity of these dyes against bacteria is fairly good.
