What is Pigment Red 22

Pigment Red 22 (C.I. 12315:1) is an organic azo pigment belonging to the β-naphthol pigment group. It typically produces a yellowish-red shade and has historically been used in conventional coloring applications such as coatings, printing inks, and certain plastic systems.

The pigment is synthesized through an azo coupling reaction between aromatic diazonium compounds and naphthol derivatives, forming an insoluble organic pigment with moderate tinting strength and color brightness. Like other pigments in the β-naphthol class, Pigment Red 22 is known for its relatively simple manufacturing process and established use in industrial coloration.

Pigment Red 22 has been applied in various formulations where a bright red tone and economical pigment chemistry are required.

Typical Limitations

Pigment Red 22 may present certain limitations depending on the performance requirements of the final application.

Typical limitations include:

Moderate lightfastness, particularly under outdoor exposure
Limited heat resistance compared with high-performance pigments
Possible bleeding or migration in some plastic systems
Not typically used in applications requiring long-term weather durability

Buyer Guidance

When selecting Pigment Red 22 for industrial formulations, several technical considerations are commonly evaluated:

Processing temperature of coatings or plastics
Lightfastness requirements for indoor or outdoor applications
Compatibility with binder or resin systems
Dispersion behavior within the formulation

Applications requiring higher durability, improved weather resistance, or greater thermal stability may evaluate other pigment classes.
