Product Description of Pigment Red 49:1:

Pigment Red 49:1 is a barium salt lake, which gives neutral red light. Due to the unsatisfactory heat resistance stability, it limits its application in plastics; it is mainly used for printing ink coloring, especially for publishing gravure ink, resinization The treated dosage form can reduce its copper light phenomenon; the special dosage form is suitable for water-based inks;  More economical pigment varieties. It is mainly used for coloring pigments such as inks and cultural and educational supplies such as watercolors and oil paints, and can also be used for paints.

Pigment Red 49:1 is a red powder with a color index name PR 49:1. It has high tinting power and has a heat resistance of 180ºC. It is ideal for use as a low cost solvent-based flexographic ink. It may also be used in cosmetic applications and self-dry paint.
