Abstract
PURPOSE: To prepare the title novel dye for dyeing of synthetic fibers in greenish yellow color having excellent color fastness to daylight and fastness to sublimation, by diazotizing an α- or β-aminoanthraquinone and coupling with a specific pyridone derivative.
CONSTITUTION: A water-insoluble pyridone azo dye of formula III is prepared by diazotizing an α- or β-aminoanthraquinone derivative, and coupling with a 3-cyano- 4-methyl-6-hydroxy-2-pyridone derivative of formula II (R1 is H, 1W12C alkyl, hydroxy-lower-alkyl, lower-alkoxy-lower-alkyl, lower-alcoxy-lower-alkoxy-lower- alkyl, lower-alkoxycabonyl-lower-alkyl, acyloxy-lower-alkyl, aryloxy-lower-alkyl, cyano-lower-alkyl, lower-alkylamino-lower-alkyl, halogeno-lower-alkyl, cycloalkyl, aralkyl, phenyl, or 2W4C alkenyl).
