Pigment Information
This color contains the following pigments:
PB15-Phthalo Blue
PY74-Hansa Yellow
PY53-Nickel Titanium Yellow
Pigment Name
PB15-Phthalo Blue
Pigment Type
organic
Chemical Name
copper phthalocyanine
Chemical Formula
C32H16CuN8
Properties
Phthalo Blues are pure and clean primary blues with superior covering power. They have a very high tinting strength and tend to overwhelm other pigments, but if color strength can be controlled, they make predictable mixed colors. In oil form, blues are very deep and slow drying. When mixed with other colors or if chlorine is added, Phthalo Blue quickly tends towards green. When using alone, mix with some white, as Phthalo Blue can be semi-transparent and almost black on its own. It is among the most compatible of modern colors with mineral colors and is considered more reliable than Prussian Blue, while sharing the same physical and color properties. Phthalo Blue is a good color for glazing.
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
PY74-Hansa Yellow
Pigment Type
monoazo
Chemical Formula
C18H18N4O6
Properties
Pigment PY74 is one of the most commercially important pigments of the Hansa Yellow group, considered superior to many others in its class based on both tinting strength and lightfastness. Several PY74 grades with different particle sizes are available. Grades with finer particle size are more brilliant and transparent. Pigment PY74 ranges from reddish yellow to greenish yellow, with temperature shifts from cool to warm hues. It has high tinting strength and average to slow drying time.
Permanence
This Hansa Yellow has better lightfastness that other yellow monoazo pigments, particularly in the darker 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.
Pigment Name
PY53-Nickel Titanium Yellow
Pigment Type
inorganic
Chemical Name
mixed metal oxide
Chemical Formula
(Ti,Ni,Sb)O2
Properties
Nickel Titanium Yellow is one of the cleanest and brightest of the inorganic pigments. It has a low tinting strength and average to slow drying time.
Permanence
Nickel Titanium Yellow has excellent lightfastness and outstanding stability with regard to chemicals, weather, and heat. It is durable in exterior conditions.
Toxicity
Nickel Titanium Yellow is not considered toxic.
History
Nickel Titanium Yellow was developed in the 1960s.
