Widely used as a red pigment in printing inks, especially for packaging and labels due to its strong color and good lightfastness. Commonly found in flexographic and lithographic inks where bright, opaque red tones are required. Also applied in some industrial coatings and colored cement products. Not suitable for food-contact applications or high-temperature processes. Its performance in water-based systems is limited, so it is mainly used in solvent-based or oil-based formulations.
