- 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
Why does PIGMENT YELLOW 150 (HP YELLOW 1541J) offer superior heat stability for water-based inkjet inks?
PIGMENT YELLOW 150 (CI 11782, azo/nickel complex) delivers heat stability up to the temperature limits of standard water-based inkjet formulations, ensuring no thermal degradation during printhead firing. This performance stems from its nickel-complex structure, which also provides good lightfastness and weatherfastness. For ink manufacturers targeting consistent jetting and long-term print durability in aqueous inks, this single-pigment solution eliminates the need for secondary stabilizers.
Can HP YELLOW 1541J be used in solvent-based coatings without compromising weather resistance?
Yes—PIGMENT YELLOW 150 exhibits good weatherfastness when formulated into solvent-based paints, industrial coatings, coil coatings, and auto paints. The azo/nickel complex resists fading under UV exposure, maintaining color strength at recommended loadings (typically 2–8 wt%). For wood coatings and powder coatings, its heat stability and lightfastness meet the demands of both interior and exterior applications.
What makes PIGMENT YELLOW 150 suitable for plastics like PP, PE, PVC, and PET?
HP YELLOW 1541J (PY150) withstands processing temperatures up to 220°C (per heat stability data), making it compatible with polyolefins (PP, PE), PVC, and PET injection molding or extrusion. Its good lightfastness prevents yellowing in consumer goods, while the nickel complex ensures minimal bleeding in xylene—critical for food-contact and packaging applications where solvent resistance is required.
How does the azo/nickel complex structure of PY150 improve lightfastness in water-based inks?
The nickel ion in the complex stabilizes the chromophore against photo-oxidation, delivering lightfastness ratings of 7–8 on the blue wool scale in standard water-based inkjet inks. This structural advantage allows ink formulators to achieve fade-resistant prints on uncoated papers and textiles without adding UV absorbers, simplifying the wetting and dispersant package.
Is PIGMENT YELLOW 150 compatible with both solvent-based and water-based printing ink systems?
Yes—PY150 is recommended for both solvent-based and water-based printing inks, including inkjet inks. In solvent systems, its specific density (2.0 g/cm³) and narrow particle size distribution ensure fast dispersion without settling. For water-based flexo/gravure inks, proper wetting agents help overcome the nickel complex’s inherent hydrophobicity, yielding stable millbases and high color saturation.
