Abstract
NEW MATERIAL:Compounds of formulaI, wherein D is a group of formula IIWVI; X is cyano, alkoxycarbonyl; Y is H, Cl, methyl, acylamino; Z is H, Cl, methyl, methoxy, ethoxy; R1, R2 are each H, (un)substituted alkyl, cyclohexyl, alkenyl, aryl; and R3WR6 are each H, alkyl.
USE: Disazo dyes which dye polyester fibers clear blue with excellent fasteness to light, sublimation and water, and have excellent temperature stability and pH stability during dyeing.
PREPARATION: An amino having the formula D-NH2 is diazotized.The resulting diazonium compd. is coupled with an aminothiophene of formula VII to produce a monoazo compd. of formula VIII. This monoazo compd. is diazotized and coupled with an aniline of formula IX.
