Pigments

Pigments are organic or inorganic colorants in platelet or powder form that cannot be dissolved. They are often of natural origin, but synthetic production is also possible. In their application, color considerations play the decisive role; there are colored pigments, black and white pigments, and colored and luster pigments. The so-called functional pigments do not represent actual colorants.

The fact that pigments appear colored at all depends on the interaction of the material with light:

  • White effect is due to non-selective light scattering.
  • Color effects are based on selective light absorption with light scattering.
  • Black effect comes from non-selective light absorption.
  • Luster pigments get their optical effect from the directional reflection of refractive transparent pigments or from metallic pigments. Interference phenomena on layers can also produce gloss effects.

Pigments are also used to color coating materials.
