This color contains the following pigments:
PY110—Isoindolinone Yellow
Pigment Type
organic synthetic
Chemical Name
isoindolinone yellow
Chemical Formula
n/a
Properties
Isoindolinone Yellow is a high performance pigment of excellent brightness and an average drying time.
Permanence
Isoindolinone Yellow has excellent lightfastness.
Toxicity
Isoindolinone Yellow is not considered toxic.
History
The first isoindoline pigments were patented in 1946, and commercial production of pigments in this group began in the 1960s. Several isoindoline yellow pigments are available.
Alternate Names
Tetrachloroisoindolinone.
PR264—Pyrrole Rubine
Pigment Type
organic
Chemical Name
1,4-diketo-3,6-di(4'-tertiary butyl phenyl)-2,5-dihydro pyrrolo[3,4-c]pyrrole
Chemical Formula
n/a
Properties
Diketo pyrrolo pyrrole pigments are noteworthy for their light stability, excellent weatherability, and outstanding heat stability.
Permanence
Pyrrole Rubine has good permanence and lightfastness.
Toxicity
Pyrrole pigments are considered to be non-toxic.
History
The Pyrrole group of synthetic organic pigments was developed in the 1980s. Pyrrole Rubine is manufactured by Ciba Specialty Chemicals under the trade name Irgazine Ruby.
Alternate Names
Irgazine Ruby
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.
