C.I. pigment red 53:1

C.I. Pigment Red 53:1, also known as Lake Red C, Lake Red CBA, and 1860 Red, is a barium-based azo lake pigment registered under CAS 5160-02-1 and EC 225-935-3. It carries no E-code designation and is classified under HS code 2927.00.5000 for customs purposes.

In printing inks, it delivers strong red hues in lithographic and flexographic systems, where the barium lake structure anchors the colorant to substrates and improves resistance to bleed. In plastics and coatings, it functions as a surface-active colorant, modifying wetting behaviour at interfaces to support uniform dispersion and film formation.

This pigment is supplied in powder or crystalline form across grades suited to printing, coatings, and polymer applications. It falls under REACH regulation and requires an up-to-date Safety Data Sheet for EU procurement. Packaging formats typically follow standard industrial conventions for organic pigments.
