摘要： A metallic polypropylene resin composition is provided herein. The metallic polypropylene resin composition provides appearance characteristics that are similar to those provided by painting, but without painting. The metallic polypropylene resin composition of the present invention has excellent physical properties such as scratch resistance, and thus may be applied to molding methods, such as a molded in color (MIC) method. The resin composition is useful as a material for automobile interior and exterior parts, as wells as electric and electronic products, which can be molded by the MIC method.
