Why do pigment CI numbers have suffixes?
A single base CI number includes various pigment grades.
Variations in crystal structure, surface treatment and manufacturing lead to different product properties.
Suffixes distinguish each variant, which differ in shade, transparency, heat and weather resistance.
Case from our color card:
✅ Pigment Yellow 74 (5GX-WHT)
✅ Pigment Yellow 74 (2GX-WOP)
Same base pigment, different suffixes → different color performance.
Remember to check the full pigment specification before selection!

Pigment Red 8 (C.I. 12335, Permanent Red F4R) is a vibrant monoazo naphthalene pigment known for its clean, bluish-red shade. It offers high tinting strength, good lightfastness, and excellent acid resistance. Commonly used in printing inks (offset, water-based), textile printing, and paper coloration, it provides a cost-effective solution for bright red applications. It is typically suitable for applications with moderate requirements for heat and solvent resistance.

When selecting organic pigments for plastics, coatings, or inks, several performance characteristics are often considered beyond just color.
1. Strong Color Strength
Organic pigments are known for their bright shades and high tinting strength, allowing vivid coloration even at relatively low dosage levels.
2. Excellent Fastness Properties
Many organic pigments offer good light fastness and weather resistance, helping colors remain stable during long-term use.
3. Good Processing Performance
Properly designed pigments can provide excellent dispersion and compatibility, contributing to smoother processing and more uniform color development.
4. Versatile Applications
From plastics and coatings to printing inks and specialty products, organic pigments play an important role in a wide range of industries and everyday applications.
Choosing the right pigment often depends on the specific performance requirements of the end application, making technical understanding just as important as color selection.
