Widely used in printing inks, especially for packaging and labels due to its strong red color and good dispersibility. Commonly found in flexographic and gravure inks where color consistency and opacity are important. Also used in some industrial coatings and plastics, though with limited heat stability, so it's not suitable for high-temperature processing. Its performance in outdoor applications is moderate, offering some resistance to fading but not ideal for prolonged UV exposure. Not used in food-contact materials or cosmetics due to regulatory restrictions.
