Pigment Information

This color contains the following pigments:

PO61-Isoindoline Orange 61

PY13-Benzidine Yellow

PG7-Phthalo Green

PO13-Vibfast Orange 4051

PY3-Hansa Yellow 10G


Pigment Name

PO61-Isoindoline Orange 61

Pigment Type

organic, azomethine

Chemical Name

isoindoline orange

Chemical Formula

Properties

Isoindoline Orange 61 is an opaque, yellowish orange pigment with moderate tinting strength.

Permanence

Isoindoline Orange 61 has very good lightfastness, although not as good as yellow pigments in the isoindoline group.

Toxicity

Isoindoline Orange 61 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. Because of its high heat stability and relatively good lightfastness, PO61 is used in plastics, automotive finishes, and for printing inks. PO61 is often compared with PO13, which has higher tinting strength, but is not as lightfast.


Pigment Name

PY13-Benzidine Yellow

Pigment Type

organic

Chemical Formula

Properties

Permanence

Benzidine Yellow has good lightfastness.

Toxicity

History


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.


Pigment Name

PO13-Vibfast Orange 4051

Pigment Type

organic

Chemical Formula

Properties

Pigment Orange PO13 is a yellowish orange with high tinting strength.

Permanence

Pigment Orange PO13 has good lightfastness when used at full strength, but it may fade in tints. It is often replaced by PO61, which has lower tinting strength, but better lightfastness.

Toxicity

History

Pigment Orange PO13 is used in inks, textiles, paints, plastics, and rubber.


Pigment Name

PY3-Hansa Yellow 10G

Pigment Type

organic, monoazo

Chemical Formula

C16H12CL2N4O2

Properties

This Hansa yellow is a transparent yellow. It has great brightness and tinting strength and its drying time ranges from average to slow. Hansa Yellow makes more intense tints and cleaner secondaries than Cadmium Yellows, especially when mixed with other organic or modern colors like Phthalo Blue and Green. Because they are more transparent, they have great value as glazing colors.

Permanence

This Hansa Yellow has fair to good permanence, particularly in the lighter shades.

Toxicity

Hansa Yellow has no significant acute hazards, though its chronic hazards have not been well studied.

History

Hansa Yellows were first made in Germany just before WW1 from a series of synthetic dyestuffs called Pigment Yellow. They were intended to be a synthetic replacement for Cadmium Yellow.
