New four acid azo dyes were synthesized from aromatic amines containing acidic group and 3-(1,3-benzothiazol-2-yl) naphthalen-2-ol by diazotization and coupling reaction. These dyes were characterized by FTIR, 1H NMR and mass spectral analysis. Effect of solvent polarity and role of pH on photo physical properties such as absorption, emission were studied. All these acid azo dyes were applied on wool, silk and nylon whereupon fastness properties were evaluated. A parallel series of dyes using 2-naphthol in place of benzothiazolyl were made to investigate the effect of benzothiazolyl moiety on the fastness and photo physical properties.
