A series of monoazo disperse dyes have been prepared by coupling 2-amino-3-carbethoxy-4,5-dimethylthiophene with various N-arylmaleimides. The monoazo disperse dyes were characterised by IR spectral studies and elemental analysis. These dyes were applied at 2 % depth on polyester fabrics and gave light yellow to brown colour hues with fair fastness to light and very good to excellent fastness to washing, rubbing, perspiration and sublimation. The percentage exhaustion of the dyebath and fixation on the fabric were found to be very good.
