What is Pigment yellow 65?
Pigment Yellow 65 (CAS 6528-34-3) is a monoazo yellow pigment; also known as PY65, of the acetoacetarylide class.
Where is Pigment yellow 65 used?
- Plastics and polymer compounding: consistent yellow coloration in rigid and flexible substrates
- Coatings: reddish-yellow tone and good hiding power in industrial paints and decorative finishes
- Printing inks: color reproducibility in solvent-based and offset packaging inks
- Textile and paper dyeing: surface coloration and pigment-printed fabric applications
- It provides bright, warm yellow hues in industrial colorant systems.
Good to know: Processing temperatures require reasonable heat stability. Particle size and surface treatment vary by grade to optimize dispersion performance.
Commercial specifications
- Standard commercial grades for plastics, coatings and inks
- Packaging in fiber drums or multi-wall bags
