Pigment Red 57:1 (C.I. 15850:1) is an organic azo pigment belonging to the BONA (β-oxynaphthoic acid) pigment class. It is the calcium salt form of Pigment Red 57 and typically produces a bluish-red shade.
The pigment is synthesized through an azo coupling reaction followed by conversion into a metal salt form. This process results in an insoluble pigment with improved stability compared with the free acid form. Pigment Red 57:1 is widely used in industrial coloration systems due to its balanced color properties and established pigment chemistry.
Because of its color tone and compatibility with many binder systems, Pigment Red 57:1 has historically been applied in coatings, printing inks, plastics, and other materials where a red pigment is required.

Pigment Red 57:1 is used in several industrial coloring systems.
Typical applications include:
Printing inks
Widely used in packaging inks, publication inks, and other conventional ink formulations.
Industrial coatings
Applied in decorative coatings and general industrial paint systems.
Plastic coloration
Suitable for certain plastics such as PVC and some polyolefins processed at moderate temperatures.
Rubber products
Used for coloring rubber materials and related industrial compounds.
The performance characteristics of Pigment Red 57:1 are influenced by its chemical structure and calcium salt composition.
Key properties include:
Color shade
Bluish-red tone with moderate chroma.
Tinting strength
Moderate to relatively strong tinting strength in many industrial formulations.
Dispersion characteristics
Can be dispersed in coatings, inks, and plastic systems using conventional dispersion processes.
Heat resistance
Moderate thermal stability suitable for certain plastic processing temperatures.
Solvent resistance
Generally compatible with solvents used in coatings and printing inks.
Establish a rigorous quality control and testing system to ensure high color saturation, strong stability, full compliance with industry standards, and consistent product quality.
Boasts high color strength, excellent light fastness (4～5 grade, 1/1 SD), and good heat resistance. Features standard magenta with a subtle bluish undertone compliant with four-color printing specifications; particle size and shade can be flexibly adjusted by adding Toluene Sulfonic Acid during synthesis, adapting to various application scenarios.
Widely used in coatings, inks, color plastics (flexible PVC, LDPE), latex paints and other industries. Legally applicable as Food Red No.7, meeting coloring needs across multiple fields.
Maintain regular stock to ensure fast delivery of standard orders; provide customization services (including particle size, shade, packaging, etc.) for large orders or personalized requirements, flexibly responding to customer needs.
Under the premise of ensuring excellent performance and stable quality, it offers high cost-effectiveness, providing customers with a cost-efficient and reliable coloring solution.
Pigment Red 57:1 may have limitations depending on the durability requirements of the application.
Typical limitations include:
Moderate lightfastness, especially in outdoor environments
Limited heat resistance compared with high-performance pigment types
Possible bleeding or migration in some plastic systems
Not typically used where long-term weather resistance is required
When selecting Pigment Red 57:1 for industrial formulations, several technical factors are often considered:
Processing temperature of plastics or coatings
Lightfastness requirements for indoor or outdoor use
Compatibility with binder or resin systems
Dispersion behavior within the formulation
Applications requiring improved durability, weather resistance, or higher thermal stability may evaluate alternative pigment chemistries.
