The present invention provides a substantially amorphous polyester resin composition, which comprises: 1 to 40 parts by weight of a core-shell modifier for impact resistance, which comprises, as a core, a bilayer aromatic vinyl-butadiene based copolymer comprising an innermost layer having a higher content in weight of a cross-linking monomer, and has a refractive index between 1.55 and 1. 60; and 60 to 99 parts by weight of at least one aromatic polyester or co-polyester, wherein the amorphous polyester resin composition exhibits high transparency, high impact resistance, and is improved in whitening properties at a low stress. |
