Pigment red 146

Pigment Red 146, also known as PR-146, C.I. 12485, Fast Red FBB, and Pigment Carmine Red, is a monoazo pigment with CAS number 5280-68-2. It belongs to the naphthol AS class of organic pigments and delivers a strong bluish-red hue with good lightfastness and heat stability across industrial substrates.

In printing inks and packaging applications, PR-146 provides high tinting strength and sharp colour reproduction on both coated and uncoated substrates, making it suitable for offset and flexographic processes. In plastics and coatings, it disperses effectively to achieve uniform surface colour with controlled wetting behaviour, supporting consistent film formation and adhesion performance.

PR-146 is supplied as a dry powder and is subject to REACH registration requirements for EU market entry. Buyers should confirm compliance documentation, including Safety Data Sheets and technical data sheets, with the supplier prior to procurement. Packaging formats typically include fibre drums or multi-layer bags depending on order volume.
