- 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 53:1
What specific performance advantages does PIGMENT RED 53:1 (HP RED 2466) offer for water-based ink formulations?
HP RED 2466 (Pigment Red 53:1, CAS 5160-02-1) delivers superior gloss and high coloring strength in water-based ink systems, making it the preferred red pigment for disposable printed products. As a barium lake pigment with EINECS 225-935-5, it exhibits strong compatibility with water-based acrylic and polyurethane resin systems, ensuring stable ink formulations with consistent rheological behavior. The pigment’s controlled particle size distribution enables both high tinting strength and smooth film formation, which are critical for achieving vibrant prints with excellent surface gloss.
How does PIGMENT RED 53:1 compare to PR57:1 in terms of shade, gloss, and application suitability for packaging inks?
PIGMENT RED 53:1 produces a deeper, slightly bluer red shade compared to the more magenta-leaning PR57:1. In water-based ink systems, PR53:1 (HP RED 2466) consistently delivers superior gloss development, which is essential for high-quality packaging prints. While both are barium lake pigments used in printing inks, PR53:1 is particularly recommended for water-based flexo and gravure inks used in disposable packaging, whereas PR57:1 is more commonly specified for offset and publication inks where different shade and gloss requirements exist.
What are the critical quality parameters to evaluate when sourcing PR53:1 for water-based ink production?
When sourcing PIGMENT RED 53:1 (C.I. 15585:1) for water-based inks, buyers should prioritize evaluating the pigment’s pH stability and electrolyte resistance, as these directly impact dispersion stability and shelf life in water-based systems. Consistent batch-to-batch color strength and gloss performance are ensured through strict control of particle size distribution and specific surface area (㎡/g). Reliable suppliers provide certified technical data sheets with density (g/cm³) and alkali/acid resistance specifications, enabling formulators to predict processing behavior and end-use performance in disposable printed products.
Is PIGMENT RED 53:1 suitable for high-strength water-based flexo inks used in packaging?
Yes, PIGMENT RED 53:1 (HP RED 2466) is specifically formulated and recommended for high-strength water-based flexo and gravure inks used in disposable packaging applications. Its high intrinsic strength allows formulators to achieve target color at lower pigment loading, reducing raw material costs while maintaining the brilliant red shade characteristic of this barium lake pigment. The pigment’s good gloss and excellent stability in water-based acrylic systems make it an ideal choice for printed products such as food wrappers, labels, and shopping bags where vibrant color and surface aesthetics are critical.
What is the recommended processing temperature range for PIGMENT RED 53:1 in water-based ink manufacturing?
PIGMENT RED 53:1 (C34H24Cl2N4O8S2Ba) exhibits heat stability up to specified temperatures in technical data sheets, making it well-suited for standard water-based ink manufacturing processes. The pigment maintains its color strength and gloss properties through typical dispersion and mixing operations at controlled temperatures below 80°C. Formulators should reference the specific heat stability data provided by the manufacturer to optimize processing parameters and ensure consistent performance in disposable printed products.
