Chemical Formula

Properties

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.

Permanence

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.

Toxicity

History

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.
