Pigment Information

This color contains the following pigments:

PR179-Perylene Maroon

PG7-Phthalo Green


Pigment Name

PR179-Perylene Maroon

Pigment Type

organic, anthraquinone

Chemical Formula

C26H14N2O4

Properties

Perylene Maroon is a transparent, dull to moderately dull, deep red pigment. Its transparency makes it useful as a glazing color.  Its mixing complement is Phthalo Green, and together they produce a pure black that is darker than most carbon-based pigments.

Permanence

Perylene Maroon has excellent permanence and lightfastness, and it can be an appropriate replacement for Anthraquinone Red in watercolor form.

Toxicity

Perylene Maroon has no significant acute toxicity. Its long term hazards are currently unknown.

History

Perylenes have been used as vat dyes since 1912, but they were not manufactured and sold as pigments until 1957.


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.
