Pigment Red 81 Applications

The red color pigment 81 gives a pure blue light red, which conforms to the magenta tone used for four-color plate overprint printing ink and has high coloring intensity. It is mainly used for coloring printing ink and cultural and educational supplies, but has low solvent resistance to polar solvents, such as alcohols, ketones and esters or their mixtures, while it is stable to aromatics, paraffin, etc.
