What is Pigment Red 49:1

Pigment Red 49:1 (C.I. 15630:1) is an organic azo pigment belonging to the BONA (β-oxynaphthoic acid) pigment class. It is the calcium salt form of Pigment Red 49 and typically produces a bluish-red to deep red shade.

The pigment is produced through an azo coupling reaction followed by conversion into a metal salt form. This process results in an insoluble organic pigment with improved stability compared with the free acid form. As a result, Pigment Red 49:1 can be used in a variety of industrial coloration systems.

Pigment Red 49:1 has historically been applied in coatings, printing inks, plastics, and related materials where a stable red color is required in conventional industrial formulations.

Advantages

Bright and Long-Lasting Shade: Features both a neutral red shade and a bright bluish-red hue, with strong tinting strength and rich, deep color. Delivers eye-catching printing results and maintains long-lasting color without fading.
Excellent Lightfastness: Retains vivid color even under strong light or long-term exposure, effectively preventing fading and ensuring long-term color stability of products.
Suitable for Water-Based Systems: Boasts excellent dispersibility and water compatibility, achieving uniform color in water-based media. It is an ideal choice for water-based printing ink applications.
Environmentally Friendly, Safe and Compliant: Strictly meets international environmental standards, free of harmful substances, safe and reliable. It not only guarantees color performance but also supports sustainable development, providing a green solution.
Strong Chemical Resistance: Resists corrosion from various chemical media, maintaining stability in diverse application scenarios and ensuring long-term durability and color permanence of products.
Versatile Application Adaptability: Widely applicable to printing inks (especially publication gravure inks and water-based printing inks), plastics, coatings, textiles and other fields. The resin-treated formulation can reduce bronzing, with high cost-efficiency, suitable for large-scale mass-market applications.

Typical Limitations

Pigment Red 49:1 may have limitations depending on the durability requirements of the application.

Typical limitations include:

Moderate lightfastness, especially under prolonged outdoor exposure
Limited heat resistance compared with high-performance pigments
Possible bleeding or migration in certain plastic formulations
Not typically selected for applications requiring long-term weather durability

Buyer Guidance

When selecting Pigment Red 49:1 for industrial applications, several formulation factors are commonly evaluated:

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

Applications requiring higher durability, improved weather resistance, or greater heat stability may consider alternative pigment chemistries.
