C.I. pigment red 81.

C.I. Pigment Red 81 (CAS 12224-98-5, EC 235-424-7) is a synthetic xanthene-based fluorescent pigment, commercially known under trade names including Consol Rose, Cerise Toner, and Conc. Pink B. It carries no E-code designation and is not approved for food contact applications.

In printing and packaging, Pigment Red 81 delivers high-chroma pink and cerise shades in offset and flexographic inks, where its fluorescent character intensifies colour under UV light. In textile and paper coloration, it is applied as a toner or lake pigment to achieve bright pink tones that standard non-fluorescent pigments cannot replicate.

Pigment Red 81 is subject to REACH registration requirements within the European Economic Area, and buyers should request a current Safety Data Sheet and confirm compliance status before procurement. It is typically supplied as a dry powder in fibre drums or multi-wall bags, with technical and standard grades available depending on application requirements.
