Pigment Blue 15:4 (C.I. 74160) is an organic pigment belonging to the copper phthalocyanine pigment family. It generally produces a bright greenish-blue shade and is widely used in printing inks, coatings, and plastic coloration.
Pigment Blue 15:4 is a β-crystal modification of copper phthalocyanine, known for its good dispersion characteristics and relatively transparent color properties. Compared with some other crystal forms in the PB15 series, Pigment Blue 15:4 is often associated with clean color tone and good processability in ink systems.
Because of the stable phthalocyanine molecular structure, Pigment Blue 15:4 exhibits balanced resistance to light, heat, and many chemical environments, supporting its use in various industrial coloring systems.
PB15:4 – DuraPrint® S6654 ⬇️TDS
It has good color strength and excellent dispersibility, specially developed for NC-based inkjet inks requiring stable viscosity and vivid print performance.

Pigment Blue 15:4 is used in several industrial coloration systems.
Typical applications include:
Printing inks
Commonly used in offset, gravure, flexographic, and packaging inks.
Industrial coatings
Used in decorative coatings, industrial paints, and general coating formulations.
Plastic coloration
Suitable for plastics such as PVC, PE, PP, PS, and ABS.
Water-based systems
Used in water-based inks and coatings requiring stable blue coloration.
The performance characteristics of Pigment Blue 15:4 are associated with its copper phthalocyanine pigment structure.
Key properties include:
Color shade
Bright greenish-blue tone.
Tinting strength
Strong tinting strength typical of phthalocyanine pigments.
Transparency
Often used where relatively transparent blue color is required, especially in printing inks.
Lightfastness
Generally provides very good resistance to light exposure.
Solvent resistance
Compatible with many solvents used in coating and printing ink systems.
High Tinting Strength & Clean Greenish Shade – Offers bright, pure color with excellent chroma and moderate opacity.
Excellent Flow and Rheology – Ensures smooth dispersion and even film formation in gravure and flexographic inks.
Superior Fastness Properties – Excellent lightfastness, heat resistance, and solvent resistance for durable applications.
Wide Compatibility – Performs well in baking enamels, toluene-based publication gravure inks, solvent-based packaging inks, and flexographic systems.
Pigment Blue 15:4 may have certain limitations depending on formulation requirements.
Typical limitations include:
Color shade and transparency may vary depending on pigment grade and dispersion quality
In some high-temperature plastic systems, other PB15 modifications may be preferred
Proper dispersion is required for consistent color development
When selecting Pigment Blue 15:4 for industrial formulations, several technical factors are typically evaluated:
Desired color shade (bright greenish-blue)
Transparency requirements in printing inks
Processing temperature in plastics or coatings
Compatibility with binder or polymer systems
Different commercial grades may vary in particle size distribution and surface treatment depending on the intended application.
