Pigment blue 1

Pigment Blue 1 (CAS 1325-87-7), also known as C.I. Pigment Blue 1, is a triarylmethane-based organic pigment delivering a bright, reddish-blue shade across a range of industrial substrates.

It is valued in colorant formulations where vivid hue intensity and tinting strength are the primary selection criteria. In printing inks, it produces high-chroma blue tones suited to packaging applications.

Visual impact drives color specification in these sectors. Coatings formulators incorporate it into architectural and industrial finishes where a clean, saturated blue is required at relatively low pigment loading.

Textile and paper dyeing operations use it to achieve consistent surface coloration, particularly in applications where cost-effective blue shading is prioritized over extreme lightfastness demands.

Plastics compounders apply it in mass coloration of polymer substrates, including packaging films and molded articles. This versatility makes it a staple in the global colorant market for various polymers.

The product is supplied as a dry powder, typically in press cake or flushed paste form for ink and coating applications. This ensures ease of integration into existing manufacturing workflows.

Technical grade is the standard commercial offering, with particle size and dispersibility specifications varying by end-use requirement. Quality control ensures consistency across different production batches.

Packaging ranges from small drums to bulk quantities depending on supplier and application volume. Proper storage in a cool, dry environment is recommended to maintain the integrity of the pigment powder.
