ABSTRACT:
In a method for producing an odor-free metallic pigment composition, a metallic pigment is ground by a wet process. The pigment is then mixed into a molten thermoplastic resin to vaporize any additives in the metallic pigment by the heat of the resin. The pigment may be dried until its solid content becomes 50-99 percent by weight before mixing into the molten thermoplastic resin.
