Perylene Pigment Red 149 (PR149) for Plastics, Fibers and Coatings
Pigment Red 149 (PR149, C.I. 71137, CAS 4948-15-6)
is a high-performance perylene-based organic red pigment developed for demanding plastic, fiber, coating and specialty ink applications.
It provides a brilliant bluish-red shade, high tinting strength, excellent lightfastness and heat stability up to under suitable processing conditions. Its low-migration characteristics and chemical resistance make it suitable for applications requiring durable and consistent red coloration.
- Brilliant bluish-red shade
- Heat stability up to 300°C
- Lightfastness up to Grade 8
- High tinting strength
- Good migration resistance in suitable systems
- Suitable for plastics, fibers and coatings

Application:
1.Plastics and Masterbatch
PR149 can be evaluated in polyolefins, PVC, PS, ABS and selected engineering plastics for masterbatch, injection molding and extrusion. It provides a brilliant bluish-red shade, high tinting strength and good thermal stability. Compatibility, dispersion and migration should be confirmed in the final polymer system.
2.Synthetic Fibers
PR149 can be evaluated for polyester and polypropylene fiber coloration where heat stability, lightfastness and consistent color development are required. Final suitability depends on spinning temperature, dispersion, filtration pressure and fiber specifications.
3. Coatings & Paints
PR149 is suitable for evaluation in selected automotive, industrial and outdoor coating systems. It provides durable bluish-red coloration with good lightfastness and chemical resistance. Final performance depends on the binder, film thickness, pigment concentration and stabilizer package.
4.Specialty Inks
PR149 can be evaluated in selected offset, gravure, flexographic and specialty ink systems. For packaging applications, migration and regulatory suitability must be assessed in the final printed structure.
5.Children's Toys & Food Packaging
The non-toxic nature and migration resistance of PR149 make it compliant with safety standards for toys and food-contact materials.
6.Packaging and New-Energy Applications
PR149 may be evaluated in packaging-related plastics, toy-related materials and selected photovoltaic or new-energy components. Regulatory, migration, optical and electrical performance must be verified according to the final product structure and applicable market requirements.
Product Advantages
