Manufacturing. It is produced by coupling diazotized aromatic amines with acetanilide or derivatives.
Use. It is one of the most permanent yellows. It was commercially available after 1957.

Arylide Yellow 5GX—commonly referenced as Pigment Yellow 74 or Hansa Yellow 5GX—is a high-performance monoazo arylide yellow pigment, renowned for its vibrant, green-tinged yellow hue and exceptional optical qualities.

Developed through the azo coupling of diazonium derivatives with acetoacetanilide, it creates a flat, intensely colored organic structure prized in both industrial and artistic media.

The pigment is semi-transparent with high tinting strength, excellent dispersibility, and low viscosity, making it extremely versatile in applications such as water-based inks, coatings, and artist paints. Its robust lightfastness and weather resistance enhance its durability for outdoor and archival use. Artists favor Arylide Yellow 5GX for glazing, layering, and blending due to its clear, radiant tone and fine handling characteristics.

In the context of cultural heritage science, the well-documented chemical profile of Arylide Yellow 5GX aids specialists in differentiating modern synthetic pigments from historical yellow lake pigments via spectroscopic analyses.
