Novel heterocyclic acid and mordent acid dyes were synthesized by the
coupling of diazonium salt solution of different aromatic amines with 2-
butyl-3-(4-hydroxybenzoyl)benzofuran. The resulting heterocyclic acid dyes
were characterized by spectral techniques, i.e., elemental analysis, IR,
1HNMR, 13C-NMR spectral studies and UV- visible spectroscopy. The dyeing
performance of all the heterocyclic acid dyes was evaluated on wool and silk
fabrics. The dyeing of chrome pre treated wool and silk fabrics showed better
hues on mordented fabrics. Dyeing of wool and silk fabrics resulted in
pinkish blue to red shades with very good depth and levelness. The dyed
fabrics showed excellent to very good light, washing, perspiration,
sublimation and rubbing fastness.
