C.I. pigment yellow 110

C.I. Pigment Yellow 110, also known as Irgazin Yellow 2RLT, Yellow RLT, and indexed under C.I. 56280, is a high-performance isoindolinone pigment with the molecular formula C22H6Cl8N4O2. It carries CAS number 5590-18-1 and EC number 226-999-5, and has no assigned E-code as it is not used in food applications.

In industrial coatings, it delivers strong opacity and heat stability in stoving enamels and powder coatings, where its chlorinated structure resists thermal degradation during cure cycles. In plastics compounding, it provides clean yellow shades with minimal migration, making it suitable for PVC and polyolefin systems. Printing ink formulators use it in packaging applications requiring lightfastness under prolonged UV exposure.

C.I. Pigment Yellow 110 is supplied as a dry powder and is subject to REACH registration requirements within the EU. Procurement teams should confirm compliance documentation, including Safety Data Sheets aligned with Regulation (EC) No 1907/2006, prior to sourcing.
