Quinacridone Pink PR122 High Performance
Chemical Family: Quinacridone

Quinacridone Pink

Pigment Red 122 (Hostaperm Pink E)

Quinacridone Pink (PR122) is a premium High Performance Pigment (HPP) known for its exceptionally clean, vivid bluish-red (Magenta) shade. Unlike cheaper Azo pigments, it offers outstanding heat stability, chemical resistance, and weather fastness, making it the industry standard for automotive finishes and high-end printing inks.

C.I. Number 73915
CAS Number 980-26-7
Light Fastness 7 - 8 (Excellent)

Product Overview

Pigment Red 122 is one of the most durable organic pigments available. Its crystal structure is stabilized by strong intermolecular hydrogen bonding, making it insoluble in almost all solvents and resistant to high heat.

  • The "M" in CMYK: PR122 is widely used as the standard process Magenta in offset and inkjet printing because of its specific shade and transparency.
  • Non-Warping: In plastics (HDPE/PP), it does not cause warping or dimensional instability during cooling, unlike many other organic red pigments.
  • Outdoor Life: Can withstand years of UV exposure without fading, ideal for exterior paints and signage.

The Science: Crystal Stability

Why is it Weatherproof?

Standard red pigments fade in the sun because UV rays break their chemical bonds. Quinacridone (PR122) is different.

  • Hydrogen Bonding: The molecules in the crystal lattice are locked together by strong intermolecular Hydrogen Bonds (N-H...O). This creates a "shield" that solvents and UV rays cannot penetrate.
  • Automotive Grade: This stability is why luxury car manufacturers use it for red and maroon metallic finishes. It survives acid rain, extreme heat, and sunlight for decades.

Industrial Applications

Inkjet & Printing

The standard Magenta pigment for water-based, solvent, and UV-curable inkjet inks.

Automotive Coatings

Used in OEM and refinish paints for high durability and transparency in metallic shades.

Plastics & Polymers

Suitable for PVC, PS, ABS, and Polyolefins. Heat stable up to 280°C for injection molding.

Architectural Paints

Used in high-quality exterior emulsion paints that require long-term warranty against fading.

Textile Printing

Used in pigment pastes for textile printing where high washing and dry cleaning fastness is needed.

Artist Colors

Premium pigment for acrylics, oil paints, and watercolors (Rose Madder hue).

Packaging Options

10 KG / 25 KG Fiber Drums

Standard export packing to protect particle structure.

20 KG Corrugated Cartons

With inner PE liners for moisture protection.

Safety & Handling Protocols

General Safety

Organic pigments are generally non-toxic but require dust control.

  • Dust: Fine powder. Use dust extraction systems and wear masks to prevent inhalation.
  • Clean Up: Difficult to clean if spilled (very fine particles). Use vacuum cleaners with HEPA filters.
  • Static: Can generate static electricity. Ground all equipment during transfer.
