Studies on synthesis and Dyeing Performance of disperse azo dyes based onSchiff base of ninhydrin and 3-amino phenol

Coupling of various diazo solution of benzene derivatives prepared some new disperse azo dyes which are based on Schiff base of ninhydrin and 3-amino phenol. The resultant dyes were characterized by elemental analyses as well as IR and NMR spectral studies. The UV-Visible spectral data have also been discussed in terms of structural property relationship. All the disperse azo dyes were applied on polyester textile fibers. The percentage dye bath exhaustion and fixation on the polyester fibers have been found to be very good. Moderate to very good light fastness and washing fastness properties were indicated by the dyied fabrics.
