Chemical Formula
Properties
Permanent Red is a common name used for the strontium salt of beta-oxynaphthoic acid (BONA) lake pigment PR:48. It is substantially bluer than other shades of PR:48. BONA pigment lakes tend to have high tinting strength, however the tinting strength of PR48:3 is only average.
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 PR48:3 has been reported to be the most lightfast of the BONA lake pigments.
Toxicity
History
Pigment Red PR48:3 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. PR48:3 is used in printing, plastics, architectural paints, and industrial finishes.
