Abstract: New 2-aminopyridine based acid anthraquinone dyes have been synthesized by condensation of bromamine acid with 2-aminopyridine to produce 1-amino-4-(2-amino pyridinyl)anthraquinone-2-sulfonic acid, which is diazotized and coupled with various naphthalene based acid coupling components to get new series of acid anthraquinone dyes. All the synthesized dyes have been characterized by elemental analysis, spectral studies and the dyeing performance on wool, silk and nylon fibres has been assessed. All the dyes give good to very good light fastness on each fibre. The percentage dye-bath exhaustion on different fibres is good and acceptable. The dyed fibres showed moderate to very good fastness to light, washing and rubbing. All the synthesized dyes have been screened for their antimicrobial activity.
