Organic Pigments for Paints, Coatings and Inks

Gone are the days, when the performance of organic pigments was not considered up to the level of inorganic pigments. They have now taken over the market once ruled by inorganic pigments.

Are you also searching for the right organic pigment for your formulation?

Explore here, the detailed knowledge on families of organic pigment used in inks, paints, and coatings. Hence, select the ideal product satisfying the requirements of your coating formulation.


Families of Organic Pigments


Organic Pigments for Inks and Coatings Organic pigments are traditionally transparent. However, modern manufacturing techniques are capable of imparting properties not previously associated with the chemical type: it is now possible to produce high opacity organic pigments.

Organic pigments are relatively new. Although, natural dyes have been precipitated on to inorganic bases (known as lakes) and used in artists' colors since the Middle Ages (e.g. madder lake and crimson lake), true organic pigments have only been known since the early years of the twentieth century. They divide in two sub-groups:

  1. One of vegetable Origin, and
  2. Other of animal origin

Most organic pigments show better transparency as dispersion improves, while in the case of the larger particle size inorganic pigments, opacity is improved by good dispersion

  • Excellent solvent resistance, chemical stability, light fastness & weatherability
  • Good heat stability & tinctorial strength


Organic Violet Pigments


Violet paints are not commonly used whereas violet pigments are. They are used to add blue tones to red paints, and red tones to blue paints, without affecting the intensity of the color.

Violet pigments can also be used to turn the yellow tint of titanium dioxide into white. Dioxazine violet is the most used violet pigment in the paint industry.

PIGMENT NAME COLOR INDEX PROPERTIES LIMITATIONS
Dioxazine violet Pigment Violet 23, 37 Excellent heat stability and solvent resistance
Good light fastness

Dioxazine violet pigments are used in a variety of paint systems:


In metallic paints, Pigment Violet 23 is more used because of its transparency and bluer shade.


Organic Orange Pigments


Yellow and Orange pigments can often be difficult to differentiate. Numerous orange pigments can be produced via similar chemistry to inorganic yellow chrome pigments, and arylamide, isoindoline, and isoindoline yellow organic pigments.

Others tend to possess chemistry which is associated with red pigments, ie.

  • Cadmium reds and molybdate
  • Beta-naphthol and BON arylamide pigments

However, the pigments listed below are orange pigments in their own right:
