- 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 180
What specific printing ink systems is PIGMENT YELLOW 180 (CAS 77804-81-0) optimized for?
PIGMENT YELLOW 180 (C.I. Pigment Yellow 180, CAS 77804-81-0) is a benzimidazolone pigment recommended primarily for metal deco inks, as well as solvent-based and water-based packaging gravure and flexo printing inks. Its greenish to medium yellow shade delivers bright color with excellent fastness properties, making it suitable for high-speed printing processes requiring heat stability up to 280°C (plastics processing). For coatings, it performs well in solvent-based, water-based, industrial, and powder coating systems.
How does PIGMENT YELLOW 180 perform in plastics applications like PP, PE, and ABS?
PIGMENT YELLOW 180 is fully recommended for coloration of polypropylene (PP), polyethylene (PE), PVC, PS/SAN, ABS, PC, POM, PBT, PMMA, and rubber/TPV. Technical data shows heat stability up to 280°C, ensuring minimal shade shift during injection molding or extrusion. The pigment’s benzimidazolone chemistry provides high light fastness and excellent weather resistance, essential for outdoor plastic products. No bleeding in xylene indicates good solvent resistance in plastic masterbatch formulations.
What is the chemical composition and CAS number of Pigment Yellow 180?
Pigment Yellow 180 has the chemical formula C36H32N10O8 and belongs to the benzimidazolone chemical class. Its C.I. Constitution Number is 21290 (PY180), and it is listed under EINECS/ELINCS number 278-368-0. The pigment is supplied in physical powder form and exhibits no bleeding in xylene, confirming excellent solvent resistance in ink and coating applications.
Can PIGMENT YELLOW 180 be used in offset inks or inkjet formulations?
Yes. PIGMENT YELLOW 180 is recommended for offset inks, solvent-based inks, water-based inks, and inkjet inks. For water-based systems, the pigment can be formulated with appropriate dispersing agents to achieve optimal color strength and stability. The bright greenish to medium yellow shade ensures high transparency and gloss in offset printing, while its heat resistance supports fast curing in UV-offset processes.
Why does PIGMENT YELLOW 180 show no bleeding in xylene, and what does that mean for application?
PIGMENT YELLOW 180 (PY180) exhibits no bleeding in xylene, meaning the pigment does not migrate or dissolve when exposed to this aromatic solvent. This property is critical for solvent-based printing inks and coatings where color purity and resistance to solvent attack are required. It also indicates excellent compatibility with solvent-based systems and long-term performance stability.
