PURPOSE: A polycarbonate-based thermoplastic resin composition is provided to have excellent scratch resistance, impact resistance, exterior appearance, and colorability by using a rubber-modified graft copolymer which comprises hydroxy-based (meth)acrylate. CONSTITUTION: A polycarbonate-based thermoplastic resin composition comprises 10-85 weight% of polycarbonate resin, 5-30 weight% of polymethylmethacrylate resin, 5-30 weight% of rubber-modified graft copolymer which comprises hydroxy-based (meth)acrylate, and 5-30 weight% of acrylic copolymer. The hydroxy-based (meth)acrylate is one or more selected from hydroxy ethyl (meth)acrylate, hydroxy methyl (meth)acrylate, 2-hydroxy propyl(meth)acrylate, and 2-hydroxybuthyl (meth)acrylate.
