Abstract
The present disclosure relates to a thermoplastic resin composition including: a diene-based graft polymer; an acrylic graft polymer; a vinyl-based polymer including a vinyl aromatic monomer unit and a vinyl cyanide-based monomer unit; a polyamide elastomer; an olefin-based polymer including a vinyl acetate monomer unit; an inorganic antibacterial agent including a metal ion supported on a glass carrier; and a zinc oxide having a BET specific surface area of 11 to 28 m2/g.
