Pigment yellow 138

Pigment Yellow 138 (CAS 30125-47-4), also known as Quinophthalone Yellow, is a high-performance organic pigment of the quinophthalone chemical class.

Where is Pigment yellow 138 used?

• Industrial and automotive coatings: bright, durable yellow shade that resists fading under prolonged UV exposure
• Plastics: incorporated into polyolefins and engineering polymers where high processing temperatures would degrade conventional yellow pigments
• Packaging inks: solvent-based and UV-curable systems
• Textile and leather finishes: surface coatings requiring sharp hue and wash resistance
• It delivers strong, greenish-yellow coloration with excellent lightfastness and heat stability.

Good to know: Color consistency and substrate adhesion are critical factors in these applications.

Commercial specifications

• Standard commercial grades aligned with colorant industry specifications
• Pre-dispersed masterbatch or flush paste formats offered by some suppliers
• Packaging commonly in fiber drums or multi-wall bags for bulk procurement
