This color contains the following pigments:
PY139—Isoindolinone Yellow
Pigment Type
organic, azomethine
Chemical Name
n/a
Chemical Formula
C16H19N5O6
Properties
Isoindolinone Yellow is a new-generation organic pigment that has a very high tinting strength and average drying time.
Permanence
Isoindolinone Yellow has excellent lightfastness.
Toxicity
Isoindolinone Yellow is not considered toxic.
History
The first isoindolinone pigments were patented in 1946, and commercial production of pigments in this group began in the 1960s. Several isoindolinone yellow pigments are available.
Alternate Names
Isoindoline.
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.
Alternate Names
Bocour Green, Cyan Green, Intense Green, Monastral Green, Phthalocyanine Green, Rembrandt Green, Thalo Green, Winsor Green.
PO43—Perinone Orange
Pigment Type
vat, anthraquinone
Chemical Name
n/a
Chemical Formula
C26H12N4O2
Properties
Perinone Orange is a strong, clean, reddish orange pigment classified as a vat pigment. It has an average drying time.
Permanence
Perinone Orange has excellent lightfastness and weatherfastness.
Toxicity
Perinone Orange is not considered toxic.
History
Perinone orange is often used in plastics and vinyls, automotive finishes, and printing inks. Its high cost limits its application to products for which superior lightfastness and weather resistance is essential. In textiles, it is used in synthetic fabrics that must survive in harsh conditions, such as tents and awnings.
Alternate Names
Perionone Orange.
