Dyeing of the hydrophobic fiber which uses pyridone type monoazo chemical compound or textile printing manner

摘要

NEW MATERIAL:Pyridone monoazo compds. of formula I (wherein X is H, halogen, an alkyl, an alkoxy, an alkylcarbonyl, an alkyloxycarbonyl, an aralkyloxycarbonyl, an alkylsulfonyl, an arylsulfonyl, carbamoyl or the like; R is an alkenyl, a cycloalkyl, phenyl, anilino or the like). USE:Dyes which have excellent dyeing quality and dyeing bath stability and can dye hydrophobic fibers such as polyamide fibers polyester fibers, etc. clear greenish yellow to orange with excellent fastness to light, wetting etc. PREPARATION:A compd. of formula II is reacted with a compd. of Z-R (wherein Z is halogen) to obtain the compd. of formula I. Alternatively, an amine of formula III is diazotized and then coupled with a compd. of formula IV to obtain the compd. of formula I.
