Product Description of Pigment Red 81:

Pigment Red 81 is a pure blue red color, which is in line with the magenta hue used in four-color plate overprint printing inks, and has high color strength. It is mainly used for coloring of printing ink and cultural and educational supplies, but it has low resistance to polar solvents, such as alcohols, ketones and esters or their mixtures, while it is more stable to aromatic hydrocarbons and paraffin wax.

C.I. Pigment Red 81, in the form of a red powder, is a triarylcarbonium dye that can be used in printing ink applications. This product has a specific gravity between 1.80 and 2.20, a bulk volume between 3.0 and 3.5 l/kg, and an average particle size between 100 and 200 nanometers.
