Azoic dye is an interesting class of dyes because of some unique characteristics. Many people who work with dye are fascinated by azoic dye, despite the fact that its current application is quite limited. Azoic colors are not ready-made dyes.

We need to combine two compounds to produce this dye. The constituent compounds are water-soluble but the final product is water-insoluble. The wash fastness property of this dye is very good because of its water insolubility. The lightfastness property is also good because of the same reason. But the rubbing fastness property is very poor. We can produce many shades from this dye. Among the red and orange color is very popular. These properties have made this dye very special. The insoluble azoic pigment was first patented by Thomas and Robert Holliday in 1880.
