Thermoplastic resin composition and molded product manufactured therefrom

A thermoplastic resin composition comprising:

• about 100 parts by weight of a rubber-modified aromatic vinyl copolymer resin;
• about 5 to about 25 parts by weight of a polyether-ester-amide block copolymer;
• about 0.05 to about 1.5 parts by weight of a silver (Ag) compound;
• and
• about 1 to about 15 parts by weight of zinc oxide,
• wherein a weight ratio of the polyether-ester-amide block copolymer to the sum of the silver compound and the zinc oxide (polyether-ester-amide block copolymer:
• silver compound+zinc oxide) ranges from about 1:0.15 to about 1:1.5, and
• wherein the thermoplastic resin composition has a virus killing time of about 20 hours or less, as measured on a specimen having a size of 5 cm×5 cm over time at 25° C. and 50% RH in accordance with ISO 21702, in which the specimen is inoculated with porcine epidemic diarrhea virus or influenza A virus fluid, and
• wherein the thermoplastic resin composition has a color variation (ΔE) of about 3 or less, as calculated according to Equation 1 based on initial color values (L0*, a0*, b0*) measured on an injection-molded specimen having a size of 50 mm×90 mm×2.5 mm using a colorimeter and color values (L1*, a1*, b1*) of the specimen measured in the same manner as above after testing for 300 hours in accordance with ASTM D4459:
