PIGMENT YELLOW 74/ HP YELLOW 1672

What Is Pigment Yellow 74 / HP YELLOW 1672

Pigment Yellow 74 (CAS 6358-31-2, CI Number 11741) is a monoazo yellow pigment derived from acetoacetanilide coupling chemistry. Its shade spans greenish to reddish yellow depending on crystal modification — the α-form gives a greenish yellow, the β-form a reddish yellow. With fine particle size (30–70 m²/g specific surface) and good light fastness (7 on the Blue Wool scale), PY74 serves as a versatile workhorse across industrial coatings, printing inks, and color toner applications where a clean, bright yellow is required.

Why Choose HP YELLOW 1672

HP YELLOW 1672 is engineered for color toner and high-performance coating applications. Its exceptionally fine particle size and very low ash content directly benefit electrophotographic toner performance — fewer impurities mean cleaner fusing, more consistent triboelectric charging, and sharper yellow reproduction across thousands of pages. In industrial coatings, the fine particle size translates to higher color strength, faster dispersion, and a brilliant greenish-yellow masstone that remains clean even at low pigment loadings. Compared to general-purpose PY74 grades, HP YELLOW 1672 prioritizes purity and particle control for applications where standard grades fall short.

Key Features

• Fine particle size (30–70 m²/g) enables rapid dispersion and high color strength in both toner and liquid coating systems
• Very low ash content — critical for toner cartridge performance where residue directly affects fusing quality and print consistency
• Greenish-yellow α-crystal form delivers the clean, bright shade preferred in CMYK toner yellow positions and high-end industrial paints
• Good light fastness for its pigment class (7 Blue Wool scale) — sufficient for indoor applications including printed packaging and toners
• Low viscosity contribution allows higher pigment loading in coating formulations without sacrificing flow or leveling

C.I.NO.: PY74

Advantage: Bright Color, low viscosity

Main Application Recommended: Color Toners, Paints

Product Description – PY74

HP YELLOW 1672 (PIGMENT YELLOW 74) is Greenish shade, mainly suggested for color toner with fine partile size, and very low ash content with brillient yellow color.

Recommended Application

Coatings: solvent based paints, water based paints, industrial coatings, powder coatings
Printing inks: offset inks, solvent based inks, water based inks, toners

Technical Data

• 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”
