Pigment Blue 15:6 (C.I. 74160) is an organic pigment belonging to the copper phthalocyanine pigment family. It generally produces a greenish-blue shade and is used in various industrial coloration systems including coatings, plastics, and printing inks.
Pigment Blue 15:6 is a stabilized β-crystal modification of copper phthalocyanine. This crystal form is designed to improve pigment stability during processing, particularly under conditions involving heat, solvents, and mechanical stress. As a result, Pigment Blue 15:6 is often selected for applications where consistent color performance is required.
Due to the inherent stability of the phthalocyanine molecular structure, Pigment Blue 15:6 exhibits balanced resistance to light, heat, and chemical environments, supporting its use in multiple industrial color applications.

Powder coatings
Used in powder coating systems requiring stable blue coloration.
The performance characteristics of Pigment Blue 15:6 are related to its stabilized copper phthalocyanine pigment structure.
Key properties include:
Color shade
Greenish-blue tone.
Tinting strength
Strong tinting strength typical of phthalocyanine pigments.
Lightfastness
Generally provides very good resistance to light exposure.
Heat resistance
Suitable for plastic processing at relatively high temperatures.
Chemical resistance
Compatible with many chemicals and solvents used in industrial formulations.
Excellent Thermal and Solvent Stability
– The E-crystal structure maintains color stability even under high temperature or in aromatic solvent environments, preventing α→β phase transition and unwanted greenish shift.
Outstanding Color Strength and Transparency
– Provides high tinting strength and brilliant chroma, ideal for systems requiring bright, transparent blue tones.
Superior Dispersion and Flow Behavior
– Ensures smooth processing and stable dispersion in high-performance inks and coatings, especially photoresist and electronic-grade applications.
Excellent Fastness Properties
– Offers superior resistance to light, heat, and chemicals, ensuring long-term color durability.
Pigment Blue 15:6 may present certain limitations depending on formulation conditions.
Typical limitations include:
Shade variation may occur depending on dispersion and formulation system
Other PB15 modifications may be preferred in certain ink systems
Proper dispersion is required for optimal color performance
When selecting Pigment Blue 15:6 for industrial formulations, several technical factors are typically considered:
Desired color shade (greenish-blue tone)
Processing temperature in plastics or coatings
Compatibility with binder or polymer systems
Dispersion characteristics within the formulation
Different commercial grades may vary in particle size distribution and surface treatment depending on the intended application.
