This paper describes the synthesis of 5-amino-6-cyano-2-phenylthieno[ 2,3-d]oxazole and its utilization for the preparation of a range of azo disperse dyes. These aryl azo disperse dyes were applied on polyester fabric and their fastness properties were evaluated. The dyes were characterized by NMR and IR spectroscopy. The visible absorption spectra of these dyes were Recorded.

Monoazo Disperse Dyes

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.
