Abstract

NEW MATERIAL:A pyridone azo dye of formula I: (R1 is H or allyl group; R2 is 4W12C alkyl, benzyl, or phenethyl group).
USE: Dyeing synthetic fibers, e.g. polyester, polyacrylonitrile, polyurethane, triacetate, and diacetate fibers in a clear greenish yellow shade.
PROCESS: An amine of formula II is diazotized and coupled with 3-cyano-6-hydroxy- 4-methyl pyride-2-one to give an azo-compound of formula IV, which is then reacted with a sulfonate of formula D-SO3R2 [D is (substituted) phenyl group] or a halide of formula R2-Z (Z is Cl, Br. or I) to form the objective compound of formula I.
