Pigment Red 185
Pigment Red 185 is a bluish red pigment. It is almost not soluble in any solvent, and it is sterilization resistance. In printing ink, PR185 has a heat resistance of 220℃/10min. It is suitable for metal decorative ink and laminated plastic film ink. Its light fastness in these two application can be grade 6-7. And it is also suitable for the coloring of soft PVC and the migration resistance is very good in soft PVC.
