Pigment Red 53:1

Pigment Red 53:1 is red pigment with yellowish shade, and it has bright color. It has good fastness and good fluidity in ink. It is much yellower than PR57:1, and is called warm red. Pigment Red 53:1 has high coloring strength and brightness, but is sensitive to acid and alkali. When PR53:1 is applied in printing ink, it shows good solvent resistance and heat stability(200℃/10min). In the application of water based gravure ink, its stbaility would decrease if react with the alkali material in base ink. In rubber and plastics, it has good heat resistance at 260℃/5min.
