Series: C

Lightfast: n/a

Pigment 1: PG7 Phthalo Green

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

Pigment name: PG7 Phthalo Green

Pigment Type: Organic

Chemical Name: Polychlorinated copper (II) phthalocyanine

Properties: Phthalo Green is a transparent, cool, bright, high-intensity colour 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 excellent base colour for mixing a range of bright greens. Phthalo Green is considered a perfect alternative to Viridian because it is intense and mixes well, and can emphasize mineral colours in various tints. However, its tinting strength is very high so that it can overpower other colours. 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.

Alternate Names: Bocour Green, Cyan Green, Intense Green, Monastral Green, Phthalocyanine Green, Rembrandt Green, Thalo Green, Winsor Green.
