Diarylide Yellow is a semi-opaque, moderately staining, intense deep reddish yellow pigment with good tinting strength.
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. Diarylide Yellow 83 is reputed to be one of the most permanent of the entire group.
Diarylide Yellow has no significant acute hazards, but chronic hazards have not been well studied.
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.

beta-oxynaphthoic acid lake, manganese salt
Permanent Red is a common name used for the manganese salt of beta-oxynaphthoic acid (BONA) lake pigment PR:48. It is more blue than other shades of PR:48, with the exception of PR48:2. BONA pigment lakes have high tinting strength.
Beta-oxynaphthoic acid (BONA) lake pigments are more lightfast than their beta-naphthol counterparts. Although their lightfastness makes them the pigment of choice in many applications, they may shift slightly in color or lose intensity under some conditions. Pigment PR48:4 is considered more lightfast and durable than other PR48 salts.
Beta-oxynaphthoic acid may have been synthesized as early as 1887. Commerical use of BONA lake pigments began in the 20th century. Pigment PR48:4 is used in packaging and plastics.
