Pigment Information
This color contains the following pigments:
PB15:2-Phthalo Blue
PR177-Anthraquinone Red
PG7-Phthalo Green
Pigment Name
PB15:2-Phthalo Blue
Pigment Type
organic
Chemical Name
copper phthalocyanine
Chemical Formula
C32H16CuN8
Properties
Phthalo Blue PB15:2 is a structural variant of Phthalo Blue PB15 that produces more greenish tones.
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
PR177-Anthraquinone Red
Pigment Type
anthraquinone
Chemical Formula
C14H8O2
Properties
Anthraquinone Red is a magenta colored pigment that is transparent and moderately intense. It tends to fade in tints and is suitable for all media.
Permanence
Anthraquinone Red has good lightfastness and permanence in its masstone, while its tint lightfastness is moderate. Overall lightfastness and permanence varies by brand.
Toxicity
Anthraquinone Red has no significant acute toxicity.
History
Anthraquinone pigments originated as textile vat dyes before being used as pigments. They became more popular with artists once it was discovered that careful preparation and grinding helped them to retain brilliance of color.
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.
