Product Description – PY14

HP YELLOW 1543 (PIGMENT YELLOW 14) is a vibrant, medium-shade diarylide yellow pigment renowned for its bright red-yellow hue, high opacity, and excellent fastness properties, including lightfastness rated at 3-4, heat resistance up to 180-200°C, and superior solvent resistance that prevents blooming or migration. In solvent-based inks, PY14 excels due to its strong transparency options, good gloss, low viscosity, and stability against overpainting and paraffin wax, making it ideal for packaging, publication gravure, and flexographic printing applications where durable, high-color-strength yellow tones are essential for vibrant, long-lasting results. Additionally, its resistance to paraffin further makes it a useful product for packaging inks.

Recommended Application：

Coatings: industrial paints, solvent based coatings
Printing inks: offset inks, solvent based inks

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”
