Introduction

Pigment Orange 34 (PO34)provides a pure yellowish-orange shade with excellent tinting strength and versatility. It is mainly used in packaging inks and textile printing coatings, offering good lightfastness (5–6, 1/3 SD) and dry-clean resistance. The pigment performs well in soft PVC and polyolefins at up to 200 °C, and in coatings, it shows very good light and weather resistance. Its opaque grade exhibits outstanding flow properties, making it suitable for agricultural and architectural paints as a cost-effective alternative to molybdate red.
