- 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 139
What specific solvent-based ink systems is Pigment Yellow 139 (HP YELLOW 15157) optimized for?
Pigment Yellow 139 (CAS 36888-99-0, Isoindoline type) is specifically optimized for solvent-based ink systems, offering controlled particle size distribution to deliver significantly different coloristic properties. In offset inks, solvent-based inks, and water-based inks, it provides a reddish yellow shade with consistent heat stability. Our technical data shows this grade (HP YELLOW 15157) achieves reliable migration resistance in PVC applications, making it ideal for solvent-based gravure and flexo printing where shade control is critical.
How does the particle size distribution variation affect coloristic properties of PY139 in solvent inks?
The wide variety of particle size distributions in solvent-based ink systems directly impacts coloristic properties such as shade, chromaticity, and opacity. According to our technical performance data, Pigment Yellow 139 (C.I. Constitution No. 36888-99-0) exhibits different heat stability, light fastness, and migration resistance based on particle morphology. For formulators, this means adjusting dispersion conditions for solvent-based ink formulations to achieve target red-yellow hues while maintaining weather resistance and mechanical stability.
What is the chemical identity and physical property baseline of Pigment Yellow 139?
Pigment Yellow 139 (CAS 36888-99-0, EINECS 253-256-8) is an Isoindoline organic pigment with chemical formula C16H10N6O6. Technically, it features controlled specific density (g/cm³), specific surface area (m²/g), resistance to acid and alkali, and measured migration resistance in PVC. These physical properties—combined with heat stability up to tested levels and light fastness ratings—validate its recommended use in offset, solvent-based, and water-based ink systems requiring consistent weathering performance.
Can Pigment Yellow 139 achieve batch-to-batch consistency in solvent-based ink production?
Yes, through ISO 9001 certified batch control testing on color strength, shade, dispersibility, and particle size distribution against internal standards. While the specific density and specific surface area values are fixed for this Isoindoline pigment, our HP YELLOW 15157 grade ensures that each batch meets the required technical performance for solvent-based inks. This eliminates shade drift in offset, water-based, or solvent-based production lines, with documented results shipped per batch.
Why does the technical data include separate ratings for weather resistance and migration resistance in PVC?
Because Pigment Yellow 139 is used across offset, solvent-based, and water-based ink systems where performance requirements differ. Weather resistance data predicts color retention under UV exposure, while migration resistance PVC data determines suitability for plasticized PVC applications. The technical sheet provides specific densities and surface area measurements to help formulators evaluate how this Isoindoline pigment will behave in solvent-based ink systems, particularly where particle size distribution influences final product durability.
