Typical Properties
Summary
Azoic Coupling Component 18 is mainly used in the production of insoluble azo dyes and in the dyeing and printing of cotton fibers, viscose fibers and some synthetic fibers. It is the main red primer for dyeing cotton fibers. The performance is similar to that of chlorophenol as, so it can be mixed to adjust the shade. Jujube red with red base B and rose red with red base RL. It is also used for dyeing vinylon, viscose fiber, silk and diacetate fiber. As-d is used as a base agent for cotton printing. It can produce orange, red, purple and blue colors with different color bases. It has low affinity to cotton and medium coupling ability. It is also used to make fast pigment and lake pigment.
