Pigment red 81

Pigment Red 81 (CAS 12224-98-5 ), also known as C.I. 45160 Lake, is a fluorescent organic pigment derived from the rhodamine 6G cation. It delivers a brilliant, high-chroma pink-red shade across a range of substrate types.

This pigment is a recognized choice where vivid color intensity is the primary performance requirement. In printing inks, particularly offset and packaging applications, it provides fluorescent brightness that standard pigments cannot achieve.

Textile and paper dyeing operations use it where surface coloration with strong visual impact is required. It is especially effective in decorative and promotional materials where high visibility is a key design factor.

Coatings formulators incorporate it into architectural and specialty paints targeting aesthetic-driven end products. In adhesives and sealant systems, it functions as a colorant where batch identification or product differentiation is needed.

The material is supplied as a dry powder, typically in press cake or flushed paste form depending on processing requirements. It is available in standard commercial grades suited to printing ink and coating applications.

Particle size and resin compatibility vary by supplier specification to meet diverse industrial needs. Technical-grade material is the predominant market offering for this specific organic pigment type.

There are currently no established food or pharmaceutical grade designations for this pigment. It is manufactured to meet rigorous industrial quality standards to ensure consistency across large production batches.
