Pigment Information

This color contains the following pigments:

PG7-Phthalo Green

PB36-Cobalt Chromite Blue Green Spinel


Pigment Name

PG7-Phthalo Green

Pigment Type

organic

Chemical Name

polychlorinated copper(II) phthalocyanine

Chemical Formula

C32H3Cl13CuN8 to C32HCl15CuN8 or C32H16CuN8Cl15 (PG7) or C32Br6Cl10CuN8 (PG36)

Properties

Phthalo Green is a transparent, cool, bright, high intensity color used in oil and acrylics. It comes from a Phthalocyanine Blue pigment where most of the hydrogen atoms have been replaced with chlorine, forming highly stable molecules.  It has similar pigment properties and permanence to Phthalo Blue. It is slow drying and an excellent base color for mixing a range of bright greens. Phthalo Green is considered a very good alternative to Viridian because it is intense and mixes well and can be used to emphasize mineral colors in various tints. However, its tinting strength is very high, so it can overpower other colors.  This pigment most closely resembles the discontinued and toxic Verdigris.

Permanence

Phthalo Greens are completely lightfast and resistant to alkali, acids, solvents, heat, and ultraviolet radiation. 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 Green has no significant hazards, but it contained PCBs (polychlorinated biphenyls) until 1982.

History

This bright blue-green was developed in 1935 and has been in use since 1938.


Pigment Name

PB36-Cobalt Chromite Blue Green Spinel

Pigment Type

inorganic

Chemical Name

Oxides of Cobalt and Chromium

Chemical Formula

Co(Al,Cr)2O4

Properties

Cobalt Chromite Blue is an opaque pigment with moderately low tinting strength.

Permanence

Cobalt salts have excellent lightfastness and temperature stability.

Toxicity

Cobalt salts are toxic when ingested or inhaled, and slightly toxic on contact with the skin. Evidence of Chromium(III) carcinogenicity is inconclusive. Chromium(III) salts appear in greenish pigments.
