Organic Pigments

• Polycyclic
• Azo (Mono- and Di-)
• Metal complexes

For each category, classical and high performances pigments are available. The performances of the pigment will depend on:

• Chemical structures
• The surface properties
• The crystallinity
• Particle size and size distribution.
