Description

Pigment Yellow 181 is a yellow pigment that belongs to the group of inorganic compounds. It is used as a colorant in paints, plastics, and textiles. Pigment Yellow 181 is made by reacting diazonium salt with hydrochloric acid in the presence of an inorganic additive. This reaction forms a diazo compound, which is then reacted with an organic solvent to form the desired pigment. Pigment Yellow 181 has been shown to be heat resistant and can be used for manufacturing polymers.
