What is Diarylide Pigment?
Diarylide pigments are organic compounds which are used as pigments in inks and associated materials. They generally are of yellow or yellow-green in color. To some level, these organic compounds have dislocated cadmium sulfide from the marketplace. They are present as yellow powders of low solubility in water.
The formation of these pigments entails the reaction of diazotized aromatic diamines with coupling components, usually derivatives of acetoacetanilide. By differing both these components, a wide array of pigments have been formed. Linked families of organic pigments are the simpler arylides that come up from the coupling of monodiazonium salts with the same coupling associates.
Varieties Of Arylide Yellow Organic Pigments
