Comparing two common azo orange pigments for paints, inks, and plastics.
PO5 and PO13 are both azo oranges but with distinct chemistry. PO5 is a monoazo orange-yellow; PO13 is a diarylide bright orange with higher tinctorial strength. Selection depends on shade target and budget.
Choose PO5 for the more reddish-orange shade in cost-effective architectural paints, packaging inks, and textile printing. The more common azo orange for general use.
Choose PO13 when you need brighter, cleaner orange shade with higher tinctorial strength for inks and packaging. Slightly stronger color development means you can use less pigment for the same color depth.
Both have Blue Wool 4-6 lightfastness — adequate for indoor paints but will fade visibly within 1-2 years outdoors. For outdoor architectural orange, use PO64 (benzimidazolone, Blue Wool 7) or PO73 (DPP, Blue Wool 7-8).
