摘要
The present invention aims to provide a masterbatch containing a large amount of an aluminum component and having high pellet strength, wherein aluminum particles retain their inherent brightness and the amount of a component which may impair the strength or appearance of a synthetic resin molded article is small. The masterbatch of the present invention contains aluminum particles, a heat-resistant wetting agent, and a resin, wherein the proportion of the aluminum particles in the masterbatch is 50 to 80% by weight, the resin has a melt flow rate of 0.2 to 60 g/10 min, and the proportion of wax having a melt flow rate of more than 60 g/10 min and a melt viscosity at 140°C of 15 to 8000 mPa·s in the masterbatch is 10% by weight or less.
