Synthesis and characterisation of a new series of pyridinone azo dyes for dyeing of synthetic fibers

Synthesis and characterisation of a new series of pyridinone azo dyes for dyeing of synthetic fibers A series of azo dye systems, namely, 5‐arylazo‐pyridin‐2‐one dye systems ( 5a‐k ), was synthesised and characterised. The effects of the structural configuration of the pyridinone dye systems on the shifts of the ultraviolet‐visible absorption maxima were investigated. The structural effects of the polyfunctionally substituted pyridinone dye systems on the intensity of colour and fastness properties of the dyed fabrics were also discussed. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Pigment & Resin Technology Emerald Publishing

Abstract

A series of azo dye systems, namely, 5‐arylazo‐pyridin‐2‐one dye systems ( 5a‐k ), was synthesised and characterised. The effects of the structural configuration of the pyridinone dye systems on the shifts of the ultraviolet‐visible absorption maxima were investigated. The structural effects of the polyfunctionally substituted pyridinone dye systems on the intensity of colour and fastness properties of the dyed fabrics were also discussed.
