What is Pigment Red 112

Pigment Red 112 (C.I. 12370) is an organic pigment belonging to the monoazo pigment class. It typically produces a yellowish-red to bright red shade and is widely used in industrial coloration applications such as coatings, printing inks, and plastics.

The pigment is synthesized through an azo coupling reaction between aromatic diazonium compounds and coupling components, forming an insoluble organic pigment. Pigment Red 112 is known for its balanced color properties and compatibility with a range of binder systems.

Due to its color brightness and versatility, Pigment Red 112 has been used in many conventional industrial formulations requiring stable red coloration.
