Description and Uses
2-hydroxy-3-naphthoic acid (BON) is coupled with diazo compounds and their calcium salts are bright red bleed resistance pigments. The somewhat higher cost manganese salt shows better exterior durability than the calcium or barium salts. The BON red pigments are characterized by an extremely high degree of color stability, resistance to acids and alkalies and are nontoxic.
