1. A thermoplastic resin, comprising:
an alkyl acrylate-alkyl methacrylate graft copolymer (A), or
the copolymer (A) and a matrix resin (B) comprising one or more selected from the group consisting of an aromatic vinyl compound, a vinyl cyanide compound, an alkyl methacrylate, and an alkyl acrylate,
wherein a total content of the alkyl acrylate present in the thermoplastic resin is from 20 to 50% by weight, and
a butyl acrylate coverage value (X) as calculated by Equation 1 below is 50 or more:
X={(G−Y)/Y}×100,  [Equation 1]
wherein G represents a total gel content (%) of the thermoplastic resin, and Y represents a content (% by weight) of butyl acrylate in the gel of the thermoplastic resin.
