All the dyes have been classified as disperse dyes. Besides their electronic spectroscopic properties, high dye-uptakes on polyester, excellent fastness properties, highly extinction coefficients, and broad solvatochromic effects have been observed in these novels disperse dyes. The derivatives of amino triazole were appropriate as pH indicator in the range of 11-13.
