SYNTHESIS AND STUDIES OF SOME QUINOLINE BASED MONOAZO DISPERSE DYES

Various disperse dyes have been prepared by coupling various diazotized coupling components with 2,4 - dihydroxy-6-methyl quinoline. All the dyes were characterized by their percentage yield and elemental analysis. IR, H1 NMR, CMR of some selected synthesized compounds have been carried out. Their dyeing performance were assessed on polyester fabric.  The percentage dye bath exhaustion were found to be good and acceptable. The dyed fibres showed poor to fairly good light fastness and good to excellent wash fastness.
