Pigment red 53

Pigment Red 53 (CAS 5160-02-1), also known as D&C Red 9 and the barium salt form C.I. Pigment Red 53:1, is an azo-based organic pigment delivering a bright, bluish-red hue across a range of industrial coloring applications. It is used primarily where strong color intensity and cost-effective red shading are required in manufactured goods. In printing inks, it produces vivid red tones in packaging, labels, and publication printing.

High tinting strength is a formulation priority for this pigment. Plastics compounders incorporate it into rigid and flexible polymer systems requiring consistent red coloration at processing temperatures. Coatings and paint formulators use it in decorative and industrial finishes where a saturated red shade is specified. In textile and paper applications, it functions as a surface colorant where pigment-based systems are preferred.

Pigment Red 53 is supplied as a dry powder, typically in both the standard acid form and the barium lake variant (53:1). These forms differ in substrate compatibility and bleed resistance during the manufacturing process. Common commercial grades are offered at high pigment concentrations suited for masterbatch, ink, and coating production. Technical-grade material is the standard market form for most industrial users.

Specifications for this product are strictly aligned to color index performance benchmarks. This ensures reliability and consistency across various batches for large-scale chemical manufacturing and distribution.
