Pigment Type
organic, disazo

C36H32Cl4N6O8
Properties
Diarylide Yellow is a semi-opaque, moderately staining, intense deep reddish yellow pigment with good tinting strength.
Permanence
Diarylide Yellow 83 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.

Toxicity
Diarylide Yellow has no significant acute hazards, but chronic hazards have not been well studied.
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
PR149-Perylene Red
Pigment Type
organic, anthraquinone
Chemical Formula
C40H26N2O6
Properties
Perylene Red is a moderately intense, semi-opaque, medium red pigment, appearing somewhere between a Cadmium Red and a Cadmium Deep Red hue. It has excellent brightness and tinting strength. Its partial transparency makes it useful as a glazing color.
Permanence
Perylene Red has good lightfastness and permanence. Its tints may darken after extended exposure to sunlight. It is not considered suitable for exterior use.
Toxicity
Perylene Red has no significant acute toxicity. Its long term hazards are currently unknown.
History
Perylenes have been used as vat dyes since 1912, but they were not manufactured and sold as pigments until 1957. For artists, they are a replacement for historic colors that were made with berries, and are significantly more lightfast.
