Patent ID: 8710134

Claim:
A (meth)acrylic resin composition obtained by heating a resin mixture comprising a (meth)acrylic-based resin (C) and a thermoplastic resin (D), wherein the (meth)acrylic-based resin (C) is obtained by polymerizing a monomer mixture (A) comprising: from 80 to 99 wt % of a linear alkyl (meth)acrylate; and from 1 to 20 wt % of tertiary-butyl (meth)acrylate, in the presence of an alkyl acrylate-based crosslinked elastic particle (B), wherein the alkyl acrylate-based crosslinked elastic particle (B) is obtained by mixing and polymerizing from 0.5 to 5 parts by weight of a polyfunctional monomer having at least two non-conjugated double bonds per molecule, with respect to 100 parts by weight of a monomer mixture comprising from 50 to 100 wt % of an alkyl acrylate monomer and from 0 to 50 wt % of an alkyl methacrylate monomer, wherein an acid value of the (meth)acrylic resin composition is from 0.2 to 0.7 mmol/g.
