Pigment Information
This color contains the following pigments:
PY152-Diarylide Yellow 152
PY3-Hansa Yellow 10G
Pigment Name
PY152-Diarylide Yellow 152
Pigment Type
organic, disazo
Properties
Diarylide Yellow is a semi-opaque, moderately staining, intense deep reddish yellow pigment with good tinting strength.
Permanence
Diarylide Yellow 152 has very good lightfastness and permanence. However, it can fade in tints, so some artists do not consider it suitable as an artists’ color. Many other diarylide yellow pigments are reported to have fair to poor lightfastness, and some are completely fugitive. Diarylide Yellow 152 is reputed to be one of the most permanent of the entire group.
Toxicity
Diarylide Yellow has no significant acute hazards, and its chronic hazards have not been well studied. PCB (polychlorinated biphenyl) contamination is possible in materials produced prior to 1982.
History
Diarylide Yellow comes from a family of azo pigments called Diarylide. These yellow hued pigments were developed around 1940 and are very important in printing inks.
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.
