Abstract

NEW MATERIAL:An azo dye of formula I (X is nitro, acetyl, or methylsulfonyl; R1 and R2 are methyl or ethyl; R3 is H or allyl).
EXAMPLE: The compound of formula II.
USE: A dye for synthetic fibers such as polyester (ether) fibers, polyamide fibers, polyurethane fibers, etc. esp. polyethylene terephthalate fibers. It dyes the fibers in clear blue to gree color with excellent fastness to sublimation and light.
PROCESS: The objective compound can be prepared, e.g. by coupling the diazonium salt of a 2-amino-3-nitrothiophene compound of formula III (e.g. 2-amino-3,5-dinitrothiophene) with an aniline compound of formula IV (e.g. 2-methoxyethoxy-5- acetylamino-N-allylaniline).
