The Commonly Used Pigment Red 146 In The Printing Inks

Pigment Red 146 is a bluish red pigment with very good solvent resistance, even compared to other group II Naphthol AS pigments. It is primarily used in printing inks, coatings, and paints. The printing ink industry uses P.R.146 for letterpress and offset inks and also in packaging gravure and flexo printing inks. P.R.146 is somewhat yellower than P.R.57:1. It therefore fails to match the standard magenta for three and four color printing. However, P.R.146 prints have the advantage of good application performance.
