Manufacturing Methods : 3-Aminobenzenesulfonic acid diazo, and (2-Methoxyphenylamino)methanesulfonic acid coupling. Then the water with sulfonic acid base, compounds (A) (coupling components is O-Anisidine with Formaldehyde and sodium sulfite and processing); 4-Nitrobenzenamine diazo, coupled with 2-Hydroxybenzoic acid, and then will the nitro reduction, compound (B). Finally the molecular A and B mixture light gasification.
Used for cotton, viscose, silk, polyamide, polyester/cotton blended fabric dyeing and printing directly, can also be used for leather, paper and ink color.
