Introduction

Pigment Red 168 (C.I. 59300; CAS 4378-61-4), chemically Dibromoanthradanthrone, is an anthraquinone-based organic pigment with a bright yellowish red hue. It boasts excellent fastness (lightfastness Grade 7, 1/3～1/25 SD; weather resistance), strong resistance to solvents, acids, migration, and sterilization, plus reliable thermal stability (220℃/10min). With 37 m²/g specific surface area, it offers good dispersion and moderate transparency, ideal for metallic systems and color matching. Widely used in high-end coatings (automotive, architectural), plastics, and water/solvent-based inks, delivering consistent, long-lasting performance.
