ABSTRACT:

The synthesis and properties of a series of disazo disperse dyes are described. The use of different coupling components does not result in significant shift of the absorption maxima of the dyes which are mainly, a wide range of brown colours. All the dyes synthesized and applied by the thermosol process on 100 % polyester fibres, afforded very good light fastness, excellent washing, crocking and perspiration fastness. The dye structures were characterized by elemental analysis and spectral methods.
