Pigment Type

Chemical Name
beta-oxynaphthoic acid lake, calcium salt
Properties
Ruby Red is a common name used for the calcium salt of beta-oxynaphthoic acid (BONA) lake pigment PR:48. It is substantially bluer than other shades of PR:48. 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.
History
Ruby Red is a lake pigment of beta-oxynaphtholic acid, a dye that resembles the common beta-Naphthol pigments. Beta-oxynaphthoic acid may have been synthesized as early as 1887. Commerical use of BONA lake pigments began in the 20th century. Ruby Red is used in printing and plastics.
