Abstract
α-(α-Quinolyl)-perinaphthoindan-1, 3-dione (quinonaphthalone)(3) was synthesized from condensation of phthalic anhydride (1) and quinaldine (2). The III was further sulfonated to obtain sodium quinonaphthalone monosulfonate (4). Dyeing quality of IV for wool has been investigated and it was found that the fixation of the dye was good, it gave clear yellow color with a strong fluorescense, showed good resistance for washing but the stability against the exposure tosunlight was poor.
