The present invention relates to an improved coloration process for thermoplastic resins using a masterbatch containing pigments. The masterbatch composition is comprising a metallocene catalysed resin as a carrier for the pigment, so as to improve the affinity between the thermo-plastic resin and the pigment to provide a better dispersion.
L'invention concerne un procédé amélioré pour la coloration des résines thermoplastiques, qui consiste à utiliser un mélange maître contenant des pigments. La composition à base de mélange maître renferme une résine catalysée par alliage organométallique, laquelle tient lieu de vecteur pour les pigments, ce qui permet d'augmenter l'affinité entre ladite résine thermoplastique et ces pigments de manière à améliorer la dispersion.
