C.I. Pigment Red 146 is primarily used in aqueous systems (packaging gravure/flexographic inks, architectural latex paints, decorative coatings) and textile printing (lightfastness level 7).  It is a high-performance alternative to Pigment Red 57:1.

In the ink field, PR146 pigment red is suitable for offset printing, UV, PA/PP/NC inks. 

In the coating field, red146 can be used for industrial coatings and wood coloring (combined with molybdenum chrome orange to make opaque red, or with pigment yellow 83/carbon black to make brown). 

In the plastic field, it is especially recommended for PVC/plasticized PVC (migration resistance), solvent-based coatings and rigid PVC products with high weather resistance requirements.
