Abstract
A series of monoazo disperse dyes were synthesized by coupling diazotized
4-amino-N-dodecyl-1,8-naphthalimide with N,N-dialkyl anilines and naphthol
derivatives. The synthesized intermediates and the dyes were characterized
using FTIR, 1H-NMR, 13C-NMR, mass spectroscopy and elemental analysis (CHN).
Visible absorption spectra of the dyes were examined in solvents of
different polarities. The electronic absorption spectra cover a wavelength
(?max) range of 515-535 nm in DMF at uniformly absorption intensity between
1.59-3.00?104 L mol-1 cm-1. The dyes gave deep and bright intense hues of
light violet, maroon, pink and neon red on polyester fabrics. The dyes
generally showed good washing and perspiration rating but poor to moderate
light fastness properties on woven polyester fabric and could be recommended
for commercial outlets.
