Widely used in printing inks, especially for packaging and labels due to its bright red hue and good opacity. Commonly found in solvent-based and oil-based ink formulations. Also applied in plastics for coloring synthetic fibers and molded objects, providing strong color performance under high processing temperatures. Limited use in paints due to poor lightfastness, but suitable for short-term indoor applications. Not recommended for automotive or exterior coatings exposed to prolonged sunlight. Used in some industrial coatings where color stability is less critical. Not suitable for food-contact materials or pharmaceuticals due to lack of regulatory approval for such uses.
