Introduction

Pigment Blue 15:6 (E-type CuPc) represents the most reddish modification of copper phthalocyanine pigments, providing a purer, cleaner, and more vivid red-shade blue compared with C.I. Pigment Blue 60. It is widely applied in high-end coatings, printing inks, plastic coloration, and photoconductive functional pigments, particularly for LCD color filter (CF) photoresist inks.

Application

Pigment Blue 15:6, a high-performance copper phthalocyanine blue, offers exceptional color quality and durability for industrial applications.
1. Vibrant & Intense Color
Delivers a rich, deep blue hue with high chroma and saturation, ideal for creating striking visual effects.
2. Excellent Light & Weather Resistance
Rated 7-8 (out of 8) for lightfastness in full shade, ensuring minimal fading even under prolonged exposure to sunlight.
Exhibits superior weather resistance (4-5 out of 5), making it suitable for outdoor applications (e.g., automotive coatings, architectural paints).
3. High Chemical Stability
Resistant to acids, alkalis, and solvents (rated 4-5 out of 5), ensuring color consistency in harsh environments.
Low migration properties (4-5 out of 5) prevent bleeding or staining in plastics and polymers.
4. Heat Resistance
Withstands temperatures up to 280°C (short-term), making it suitable for high-temperature processing (e.g., plastic extrusion, injection molding).
5. Versatile Compatibility
Easily dispersible in various media, including paints, coatings, plastics, inks, and textiles.
Compatible with most binders and resins, simplifying formulation in diverse applications.
6. Cost-Effective Performance
Balances premium quality with cost efficiency, offering long-lasting color without excessive expense.
7. Environmental Compliance
Meets global regulatory standards (e.g., REACH, RoHS) for safe use in consumer products.

Advantages

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.
