- 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 VIOLET 3
What is the main application of Pigment Violet 3 (C.I. 42535:2)?
Pigment Violet 3, C.I. 42535:2, is primarily recommended for solvent-based printing inks, including flexographic and gravure packaging inks. It delivers a strong bluish violet shade that is considerably bluer than PV1 and PV2, making it suitable for high-color-strength ink formulations. The product also works in oil-based systems and offset inks, but its solvent-based performance is the key differentiator.
How does Pigment Violet 3 compare to Pigment Violet 1 and 2 in shade?
Pigment Violet 3 (PV3) exhibits a considerably bluish violet shade compared to PV1 and PV2. This difference makes PV3 ideal for applications requiring a cleaner, colder violet tone, particularly in packaging gravure and flexo inks where shade consistency is critical. The EINECS/ELINCS number and C.I. Constitution No. remain specific to PV3’s molybdatetungstatephosphate chemistry.
Is Pigment Violet 3 suitable for coatings?
Yes, Pigment Violet 3 is recommended for solvent-based coatings. Its light fastness and heat stability up to 200°C (typical for PV3 class) support use in industrial and decorative coatings where solvent resistance and color retention are important. Always verify the specific density (~2.0 g/cm³) and specific surface (~40 m²/g) for dispersion optimization in your coating system.
What are the bleeding characteristics of Pigment Violet 3?
Pigment Violet 3 shows bleeding in xylene and methyl ethyl ketone (MEK), which is consistent with its chemical type (molybdatetungstatephosphate). This means its use in high-solvent-resistance formulations (e.g., automotive or industrial coatings) should be tested under actual conditions. The bleeding data is provided per batch to aid solvent-based ink and coating formulators in system selection.
What physical properties should I consider for Pigment Violet 3 in solvent-based inks?
Key physical properties include a specific density of ~2.0 g/cm³, specific surface of ~40 m²/g, and physical form as a powder or granular product. These properties affect dispersion, settling, and rheology in solvent-based ink vehicles. For flexo and gravure inks, the specific surface influences color strength and transparency, while density impacts pigment loading and stability.
