Pigment yellow 73

Pigment Yellow 73 (CAS 13515-40-7), sold commercially as Hansa Brilliant Yellow 4GX and Hancock Yellow 73, is a monoazo organic pigment delivering a bright, greenish-yellow hue across a range of industrial colorant applications.

It is valued by formulators for its strong tinting strength and compatibility with multiple substrate types. In plastics and polymer processing, it is used to color polyolefins, PVC, and engineering resins.

Consistent batch-to-batch hue is critical for product specification in these industries. Coatings formulators incorporate it into architectural, industrial, and decorative paints where clean yellow shades are required at moderate cost.

Printing ink manufacturers use it in offset, flexographic, and packaging inks, particularly where brightness and printability on paper and board are priorities. This ensures high-quality visual results for consumer packaging.

Textile and leather finishing operations apply it in pigment printing pastes and surface coatings to achieve yellow tones on fabric and treated leather goods. It provides reliable performance across various textile substrates.

Pigment Yellow 73 is supplied as a dry powder, the standard commercial form for dispersion into solvent-borne, water-borne, and UV-curable systems. This versatility allows for broad application in modern manufacturing.

Press cake forms are available from select suppliers for wet dispersion processes in ink and coating production. It is typically offered in technical and industrial grades, with specifications aligned to standard colorant performance benchmarks.

The product is manufactured to meet rigorous industrial requirements rather than pharmacopeial standards like USP, FCC, Ph.Eur., BP, EP, or ACS. This makes it ideal for heavy-duty industrial use.
