Technical Data:

• Light fastness: Light fastness rating is assessed on 1 to 8 Blue Wool scale where 1 = ‘Poor’ and 8 = ‘Excellent’.
• Heat Stability : Heat stability values given indicate the maximum temperature at which the pigment can be stoved for 10 min. on the full shade and in reductions without undergoing any significant change in shade.
• Oil absorption: The oil absorption is determined on the basis of EN ISO 787-5 and given in g linseed oil per 100 gm. pigment.
• Solvent bleeding: The bleeding in solvents is tested using the powder grades and the visual rating given on 1 to 5 Grey scale
  where 1 = ‘Heavy bleeding’ and 5 = ‘No bleeding”

Frequently Asked Questions — PIGMENT YELLOW 150

What specific applications benefit from the high transparency of Pigment Yellow 150 (HP Yellow 1541)?

Pigment Yellow 150 (C.I. PY150, HP Yellow 1541) is an azo/nickel complex pigment with high transparency and good gloss, making it particularly effective for inkjet inks and paper colorants where brilliant, clean shades are required. In water-based ink systems, it delivers vibrant yellow hues with outstanding transparency, ideal for overlays and packaging printing. Beyond inks, it also performs well in solvent-based and water-based paints, industrial coatings, powder coatings, coil coatings, auto paints, and wood coatings, offering reliable color development across diverse binder systems.

How does Pigment Yellow 150 (PY150) perform in water-based inkjet inks compared to other yellows?

For water-based inkjet inks, Pigment Yellow 150 (PY150) provides a unique combination of high transparency and good gloss, which is critical for achieving sharp print resolution and vivid color reproduction. As an azo/nickel complex, it exhibits good heat stability and lightfastness, ensuring printed images resist fading under UV exposure. In Japan and Germany, where high-performance inkjet formulations are standard, PY150 is often selected for its consistent dispersion behavior and color purity. For plastic applications like PP, PE, PVC, and PET masterbatch, it also offers reliable thermal stability during processing.

Is Pigment Yellow 150 (HP Yellow 1541) suitable for solvent-based industrial coatings?

Yes, Pigment Yellow 150 (HP Yellow 1541, CAS EINECS/ELINCS available) is recommended for solvent-based paints and industrial coatings, where its azo/nickel complex chemistry delivers good weatherfastness and lightfastness. It shows no bleeding in xylene, making it compatible with common solvent systems used in automotive OEM and refinish coatings. In coil coatings and wood coatings, the pigment maintains color strength and gloss retention even under demanding application conditions. For optimal performance in both solvent-based and water-based systems, we recommend testing at typical loading levels of 5–15% depending on target shade depth.

Can Pigment Yellow 150 be used in rigid PVC and plastic masterbatch applications?

Yes, Pigment Yellow 150 (PY150, HP Yellow 1541) is applicable in plastics including PP, PE, PVC, and PET, with heat stability up to 240–260°C depending on resin system. In rigid PVC profiles and fittings, it provides good lightfastness and migration resistance, ensuring long-term color consistency in outdoor applications. For plastic masterbatch (e.g., 1:10 letdown ratio), the pigment disperses readily with standard twin-screw compounding. Its specific density and physical form are optimized for even incorporation into polyolefin and engineering thermoplastic matrices.

What technical performance data supports PY150 for outdoor weather resistance?

Pigment Yellow 150 (C.I. Constitution No. 596001) exhibits good weather resistance and lightfastness rated 7–8 on the blue wool scale (1–8 scale) in full-shade formulations, making it suitable for exterior coatings and signage. In automotive paint testing (SAE J1960), it maintains >90% gloss retention after 1000 hours QUV exposure. For paper colorants and inkjet inks, its heat stability of 240°C ensures compatibility with high-speed drying processes. Physical properties including specific density (~1.5–1.7 g/cm³) and particle size distribution are documented per ISO 9001 batch records for every shipment.
