Orange S
Strong orange coloration for paper and cellulosic applications.
Overview
Orange S is a direct orange dye used to produce orange to reddish-orange shades. Its water-soluble direct-dye character makes it suitable for industrial coloration of paper and cellulosic substrates. It shares its general azo-dye class with other direct oranges, dissolving readily to a reddish-orange solution and finding use across cotton, viscose, wool, silk, leather, and paper substrates.
