Pigment Information
This color contains the following pigments:
PY1-Hansa Yellow G
PW20-Mica
Pigment Name
PY1-Hansa Yellow G
Pigment Type
organic, monoazo
Chemical Formula
C17H16N4O4
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
Hansa Yellow G has good permanence and lightfastness, particularly in the lighter shades.
Toxicity
Hansa Yellow pigments have no significant acute hazards, though chronic hazards have not been well studied.
History
Hansa Yellows were first made in Germany just before World War I from a series of synthetic dyestuffs called Pigment Yellow. Hansa Yellow G, introduced in 1910, was the first of these products to be commercialized. Hansa Yellow G was the standard yellow for printing inks until late in the 20th century, when stronger diarylide yellows began to replace it. It is still used a great deal in packaging, and for air drying paints.
Pigment Name
PW20-Mica
Pigment Type
inorganic
Chemical Name
aluminum silicate
Chemical Formula
H2KAl3(SiO4)3
Properties
An off-white pigment with complex reflective effects, mica is often used with transparent pigments to create mixed pigments with interference and pearlescent effects.
Permanence
Mica is permanent and lightfast.
Toxicity
Although it is completely non-toxic and not bioreactive, fine particles may be irritating. This is of concern primarily for those exposed occupationally to dry mica powder. Breathing mica particles may cause lung fibrosis and pneumoconiosis.
History
Mica has been used as a pigment since prehistoric times.
