In this paper, two novel alkali clearable disperse dyes were synthesized. 4-flourosulfonyl aniline and 2-nitro-4-flourosulfonyl aniline were utilized as the diazo components and 2- naphthol as the coupling component. The DSC, FTIR, 1HNMR and UV-Vis analyses were used to characterize the synthesized intermediates and dyes. The synthesized dyes were used to dye polyester fibers and their dyeing p...
