- 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 RED 149
What is the primary application for PIGMENT RED 149 (CI 149) in plastics?
PIGMENT RED 149 (CAS Reg.-based, C.I. Constitution No. 71137) is a medium to slightly bluish red organic pigment designed primarily for plastic masterbatch and compounding. It excels in PP, PE, PVC, PS/SAN, ABS, PC, POM, PA, PET, PBT, PMMA, and elastomers like TPV, SBC, TPO, and TPU. The pigment delivers exceptionally high heat stability (up to 300°C depending on resin) and very good light fastness, making it a workhorse for automotive interior, appliance, and packaging applications where migration resistance in PVC is critical.
How does PIGMENT RED 149 perform in solvent-based and water-based coatings?
PIGMENT RED 149 is recommended for both solvent-based paints (industrial, automotive refinish, wood coatings) and water-based paints when combined with appropriate dispersing additives. In solvent systems, it provides strong color strength and weather resistance. For water-based formulations, the pigment’s chemical type (perylene) requires optimized wetting agents to achieve full color development and stability. It is also suitable for powder coatings, delivering consistent shade and thermal stability during curing cycles.
Can PIGMENT RED 149 be used in printing inks for offset or solvent systems?
Yes, PIGMENT RED 149 is applicable in offset inks, solvent-based inks, and water-based inks. For offset applications, the pigment offers good bleed resistance in xylene and methyl ethyl ketone (as per physical property data), ensuring print stability. In solvent-based systems, its heat stability supports high-speed drying processes. For water-based inks, pre-dispersion with non-ionic surfactants is advised to achieve optimal rheology and gloss.
What technical data supports the heat stability and light fastness of PIGMENT RED 149?
PIGMENT RED 149 exhibits excellent fastness properties: heat stability up to 300°C (suitable for engineering plastics like PC, POM, and PA) and very good light fastness (rated 7-8 on the blue wool scale depending on substrate). Physical properties include specific density ~1.4 g/cm³ and low bleeding in xylene and methyl ethyl ketone. These parameters, validated by ISO 9001 batch testing, make it reliable for long-life exterior and high-temperature applications.
Why is PIGMENT RED 149 preferred for polyolefins and PVC masterbatch?
PIGMENT RED 149 delivers exceptional migration resistance in PVC (rated very fast to migration) and outstanding heat stability for polyolefins (PP, PE). Its slightly bluish red shade allows formulators to achieve deep reds and blends with organic yellows (e.g., PY83 or PY110) while maintaining transparency in film applications. The pigment also shows good compatibility with recycled polyolefin streams, making it cost-effective for packaging and automotive interiors with stringent lightfastness requirements.
