Description
Summary: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 color 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. Opisana je sinteza 3-amino-4-feniltieno_2,3-c_izotiazola i etil-3-amino-4-feniltieno [2,3-c]izotiazol-5-karboksilata i njihovo koriscenje za dobijanje celog niza azo disperznih boja. Ove nove boje su proucavane sa gledista medjusobnog odnosa strukture i boje. Ispitana je i primenljivost ovih boja na poliestarske materijale kao i njihovu trajnost. Boje su karakerisane pomocu NMR, IR i vidljive apsorpcione spektroskopije.
