Abstract
An acrylic-imide copolymer including: an alkyl (meth)acrylate-based monomer unit; an aromatic vinyl-based monomer unit; and an imide-based monomer unit, wherein the copolymer includes a plurality of copolymer chains, a glass transition temperature is 109° C. to 133° C., the imide-based monomer unit is included in an amount of 20 parts by weight or less based on 100 parts by weight of an entire copolymer, and a residual monomer content in the copolymer is 1.3 wt % or less.
