To provide a thermoplastic resin composition for of mold products capable of applying ornamental processing such as coating, plating or the like without applying a specific processing such as primer process or the like on a mold product as an interior or exterior for automobile, capable of forming a mold products having desired dimensional accuracy by using a mold assembly for polypropylene resin(PP) because the resin composition has rate of mold shrinkage and coefficient of linear expansion same to PP, and provide parts for automobile obtained by coating, plating or the like on the mold products of this thermoplastic resin composition.
This composition includes (A) a rubber including graft copolymer obtained by graft polymerizing a vinyl monomer to a rubber polymer and (B) a hard copolymer obtained by copolymerizing an aromatic vinyl monomer, vinyl cyanide and other monomer if desired, and the total content of the rubber is 25-60 wt.%. The parts for automobile are obtained by applying an ornamental processing such as coating or plating or the like on the molded products of this thermoplastic resin composition.
