Abstract
The present invention relates to a high-gloss polymethylmethacrylate-acrylic copolymer alloy composition and a molded article. According to the present invention, provided are a high-gloss polymethylmethacrylate-acrylic copolymer alloy composition which provides improved surface gloss and transparency (color) while providing mechanical strength, workability, and scratch resistance required in the high-gloss polymethylmethacrylate-acrylic copolymer alloy composition by combining a specific amount of an acrylic impact modifier, as an impact modifier of an alloy of a polymethylmethacrylate resin and an acrylic copolymer, with a scratch modifier and are economically efficient by omitting a process after injection (painting process), and a molded article obtained from the same.
