Thiophene based monoazo disperse dyes for polyester fabric
A series Bag 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 fastne
