Masterbatch containing titanium oxide

摘要

A masterbatch which comprises a thermoplastic resin containing titanium dioxide. The titanium dioxide contains 0.02 to 1.0 wt.% aluminum and has been undergone a surface treatment with a specific agent. The masterbatch hence has a high whiteness and an excellent thermal stability, and is greatly reduced in the content of water evaporating in a high-temperature treatment.
