Abstract
NEW MATERIAL:The compound of formulaI[X is H, Cl, Br, methyl, etc.; Y is H, Cl, methyl, methoxy, etc.; R is H, cyclohexyl, aryl, alkyl (when both X and Y are H, then methyl, propyl, etc.), hydroxy-substituted lower alkyl, etc.].
EXAMPLE: The compound of formula II.
USE: For dyeing polyester fibers in clear reddish blueWblue color having excellent fastness to light, sublimation, etc. It has excellent stability to the temperature and pH in dyeing.
PROCESS: The objective compound can be prepared e.g. by diazotizing aniline and coupling with 2-amino-3-cyanothiophene of formula III to produce the monoazo compound of formula IV, and diazotizing and coupling the monoazo compound with the aniline compound of formula V.
