| dc.description.abstract | The reaction of ethyl-4,6-dihydroxy-2-oxo-1-phenyl pyridine-3-carboxylate (3) with different diazotized substituted aromatic amine (2) yielded compound ethyl-4,6-dihydroxy-2-oxo-1-phenyl-5-arylazopyridine-3-carboxylate (4) showing visible light absorption between lmax 550-600 nm which shows the characteristic of azo dyes. Aqueous solution of (4) with non-ionic dispersing agent a dye carrier at pH 5-6 at the temperature 130 ºC when applied to polyester fiber formed yellow to orange color. | en_US |
