Application
Pigment Orange 5 (P.O. 5, Permanent Orange RN), a β-naphthol monoazo pigment, is a versatile organic pigment that provides a bright, semi-transparent reddish-orange shade with good lightfastness (Grade 6-7) and heat stability up to 160–200°C. This pigment grade offers high color strength, excellent transparency, and good resistance to water, oil, acid, alkali, and solvents. Permanent Orange RN is widely used in offset printing inks, water-based flexo and gravure inks, solvent-based packaging inks, and UV-curable ink systems. In paints and coatings, it is formulated into automotive finishes, industrial paints, powder coatings, coil coatings, and decorative architectural paints. The pigment is also suitable for coloring engineering plastics including PVC, PP, PS, ABS, and EVA rubber for masterbatch applications, as well as for pigment printing pastes for textiles. It complies with FDA, REACH, EN71-3, and RoHS regulations for safety.
