- 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 specific performance advantages does Pigment Violet 3 (HP VIOLET 6464) offer for water-based printing inks?
Pigment Violet 3 (CI 42535:2, CAS 1325-24-6, EINECS 215-406-0) provides a very bluish shade that is considerably bluer than PV1 and PV2, with lightfastness superior to PV27. Recommended primarily for water-based inks, it also suits offset inks and water-based coatings. Its molybdatetungstatephosphate chemistry delivers heat stability and weather resistance suited for indoor durable applications.
How does the shade of HP VIOLET 6464 (PV3) compare to other violet pigments in the CI Pigment Violet family?
HP VIOLET 6464 (PV3) is described as a very bluish shade, distinctly bluer than PV1 and PV2. Formulators can use PV3 to achieve cleaner violet shades in water-based ink systems where PV27’s lower lightfastness would be a limitation. This makes PV3 ideal for shade-critical applications like high-gloss water-based packaging inks.
Can Pigment Violet 3 be used in offset printing inks, and what application-specific benefits does it bring?
Yes, Pigment Violet 3 (HP VIOLET 6464) is recommended for offset inks alongside water-based inks. Its molybdatetungstatephosphate backbone provides good transparency and bluish mass tone. The pigment’s lightfastness advantage over PV27 ensures offset prints maintain color stability in light-exposed end uses like posters or folding cartons.
What physical properties of PV3 influence its dispersibility and rheology in water-based coating systems?
Pigment Violet 3 (HP VIOLET 6464) has a specific density of [density data from supplier] g/cm³ and specific surface area of [specific surface data] m²/g. These properties, combined with its chemical type (molybdatetungstatephosphate), affect wetting and dispersion stability. For water-based coatings, selecting appropriate dispersing agents with acid value >50 mg KOH/g can optimize color development and minimize bleeding in aggressive solvents like methyl ethyl ketone.
Is Pigment Violet 3 suitable for formulations requiring minimal bleeding in xylene or ketone solvents?
Pigment Violet 3 (HP VIOLET 6464) undergoes bleeding tests in both xylene and methyl ethyl ketone. While specific bleeding resistance data should be verified for each application solvent, the pigment’s molybdatetungstatephosphate chemistry typically offers moderate solvent resistance. For solvent-sensitive systems, confirm compatibility using the bleeding grades listed in the technical datasheet.
