Organic pigments refer to a wide range of chemical families and cover a wide spectrum of properties. They are mainly used for applications needing high tinting strength and brilliant shades while inorganic pigments are mainly useful where high opacity is needed.

We can distinguish three main categories of organic pigments:

PolycyclicAzo (Mono- and Di-)Metal complexes

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

Chemical structuresThe surface propertiesThe crystallinityParticle size and size distribution.
