Pigment Red 81

Pigment Red 81 (CAS 75627-12-2), also supplied as Pigment Red 81:2, is a fluorescent xanthene-based organic pigment that delivers intense, bright red-to-pink coloration across a range of industrial substrates.

Its high tinctorial strength and fluorescent character make it a preferred choice where visual impact and color brilliance are primary formulation targets for manufacturers and chemical processors.

In printing inks, particularly offset and packaging inks, this pigment produces vivid, eye-catching hues suited to consumer-facing printed materials where color saturation drives shelf appeal.

Plastic coloration applications use it to achieve bright pink and red shades in films, molded articles, and packaging components. Textile and paper dyeing operations incorporate it for fluorescent brightness.

Coatings and adhesive formulations targeting decorative or specialty end uses also draw on its strong color yield to minimize pigment loading while maintaining the target shade and performance.

The material is supplied as a dry powder, typically in fine-milled form to support dispersion into liquid systems. It is available in technical and commercial grades for various industrial needs.

Particle size and surface treatment specifications vary by intended end use. Masterbatch-ready and pre-dispersed paste formats are offered by some suppliers to serve plastics and ink processors directly.
