The paper describes the synthesis of 3-amino-4-phenylthieno[2,3-c]isothiazole and ethyl 3-amino-4-phenylthieno[2,3-c]isothiazole-5-carboxylate and their utilization to prepare a range of azo disperse dyes. These novel aryl azo dyes were studied with respect to their colour and constitution relationship. The application of these dyes on a polyester fabric and their fastness properties were evaluated. These dyes were characterized by NMR, IR and visible absorption spectroscopy.
