Pigment Information

This color contains the following pigments:

Phthalo Blue

Zinc Sulphide White


Pigment Name

Phthalo Blue

Pigment Type

organic

Chemical Name

copper phthalocyanine

Chemical Formula

C32H16CuN8

Properties

Phthalo Blues are pure and clean primary blues with superior covering power. They have a very high tinting strength and tend to overwhelm other pigments, but if color strength can be controlled, they make predictable mixed colors. In oil form, blues are very deep and slow drying. When mixed with other colors or if chlorine is added, Phthalo Blue quickly tends towards green. When using alone, mix with some white, as Phthalo Blue can be semi-transparent and almost black on its own. It is among the most compatible of modern colors with mineral colors and is considered more reliable than Prussian Blue, while sharing the same physical and color properties. Phthalo Blue is a good color for glazing.

Permanence

Phthalo Blues are completely lightfast and stable and are permanent for all paint uses. They are currently used in inks, coatings, and many plastics due to their stability and are considered a standard pigment in printing ink and the packaging industry.

Toxicity

Phthalo Blues have no significant hazards, although those made before 1982 contained some PCBs (polychlorinated biphenyls).

History

Developed by chemists using the trade name Monastral Blue, the organic blue dyestuff now known as Phthalo Blue was presented as a pigment in November 1935 in London. Its discovery was accidental. The dark color was observed in a kettle where a dye was being made from a British dyestuff plant. The demand for such a pigment came from commercial printers who wanted a cyan to replace Prussian Blue.


Pigment Name

Zinc Sulphide White

Pigment Type

inorganic

Chemical Name

zinc sulfide

Chemical Formula

ZnS

Properties

Zinc Sulphide White is a semi-transparent yellowish white pigment. Zinc sulfide and zinc oxide (PW4) are often combined to create a more natural white color. Transparency increases as particle size decreases. When slight impurities are added, zinc sulphide has phospherescent and electroluminescent properties. It is often used to manufacture fluorescent or glow-in-the-dark paints.

Permanence

Zinc Sulphide White has excellent permanence and lightfastness.

Toxicity

Zinc Sulphide is non-toxic, but ore deposits often contain lead. Traces of lead and other impurities may be present in pigment powders. Ingestion is not recommended.

History

Zinc sulfide, when combined with slight impurites, has phospherescent properties. It is often used for "invisible ink" that glows with exposure to ultraviolet light. Zinc sulfide is used in the manufacture of fluorescent paints.
