Pigment Red 48:1 (C.I. 15865:1) is an organic azo pigment belonging to the BONA (β-oxynaphthoic acid) pigment family. It is the calcium salt form of Pigment Red 48 and typically produces a bluish-red to medium red shade.
This pigment is produced through an azo coupling reaction followed by metal salt formation, which improves pigment stability and reduces solubility. As a result, Pigment Red 48:1 forms an insoluble organic pigment suitable for use in coatings, printing inks, plastics, and other industrial coloration systems.
Due to its balanced color tone and conventional pigment chemistry, Pigment Red 48:1 has been widely used in industrial formulations where a stable red shade is required.

Pigment Red 48:1 is used in various industrial coloring systems.
Typical applications include:
Industrial coatings
Applied in general industrial paints and decorative coatings.
Printing inks
Used in packaging inks, publication inks, and other conventional printing ink formulations.
Plastic coloration
Suitable for some general-purpose plastics such as PVC and polyolefins under moderate processing temperatures.
Rubber products
Used for coloring rubber materials and related industrial compounds.
The performance characteristics of Pigment Red 48:1 depend on its chemical structure and salt form.
Key properties include:
Color shade
Bluish-red to medium red tone.
Tinting strength
Moderate to relatively strong tinting strength compared with traditional azo pigments.
Dispersion characteristics
Can be dispersed in coating, ink, and plastic systems using standard dispersion methods.
Heat resistance
Moderate thermal stability suitable for certain plastic processing conditions.
Solvent resistance
Generally compatible with common solvents used in coating and printing ink systems.
1.Color Performance
PR48 Series (Barium Salt Lake) features core hues ranging from bright yellowish to neutral red, with balanced and outstanding color performance. PR48:1 offers vivid, full colors along with high color strength and saturation. PR48:2 and PR48:3 also deliver vivid colors.
2.Weather & Light Fastness
It demonstrates prominent weather and light fastness. PR48:1 has good light and weather fastness, suitable for applications requiring long-term exposure to light.
3.Core Performance & Applications
The series delivers stable and reliable core performance, with good solvent resistance and chemical stability across the board. PR48:1 can withstand high temperatures of 200～240℃ for 5 minutes in polyethylene (PE). When applied to flexible PVC, it offers superior migration resistance, no blooming, and a lightfastness grade of 3. Suitable for gravure inks, plastic processing, and non-high-end coatings, it features excellent varnish resistance in coating applications—PR48:1 achieves an enhanced lightfastness grade of 5～6, with a wide range of applications.
Pigment Red 48:1 may present certain limitations depending on the application requirements.
Typical limitations include:
Moderate lightfastness, particularly for outdoor exposure
Limited heat resistance compared with high-performance pigments
Possible bleeding or migration in some plastic formulations
May not be suitable for applications requiring long-term weather resistance
When selecting Pigment Red 48:1 for industrial formulations, several technical considerations are typically evaluated:
Processing temperature of plastics or coatings
Lightfastness requirements for indoor or outdoor use
Compatibility with resin or binder systems
Dispersion performance within the formulation
For applications requiring higher durability, weather resistance, or thermal stability, alternative pigment chemistries may be considered.
