organic, monoazo
beta-oxynaphthoic acid lake, barium salt
Permanent Red is a common name used for the barium salt of beta-oxynaphthoic acid (BONA) lake pigment PR:48. It is more yellow than other shades of PR:48. 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 PR48:1 has poor resistance to soap, alkali, and acid, and it is less lightfast than other BONA lake salts. It loses lightfastness when it is used in combination with titanium dioxide.
Permanent 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. Permanent Red is used in industrial paints and plastics.

This Naphthol Red is a bright deep red with bluish undertones. It has an average drying time.
This Naphthol Red has fair to good lightfastness, not because of its masstone, but because it fades in tints. Not suitable for exterior use.
