Azoic Dye & dyeing process of fabric with Azo dye Azoic Coupling Most of the azoic coupling components are arylides of beta-oxynaphthoic acid (BON) also referred as Brenthols. Any azoic coupling component can be combined with any diazotized base ,so that 30 different Naphtholand 50 bases,can yield 1500 possible combinations. Naphthols […]
