PROBLEM TO BE SOLVED: To provide a thermoplastic resin composition having excellent transparency, scratch resistance and molded product appearance which comprises a polycarbonate resin and a specific acrylic copolymer.SOLUTION: There is provided a thermoplastic resin composition which comprises (C) 0.1 to 3 pts.wt. of an ultraviolet absorbing agent (C component) having a 5% weight reduction temperature in TGA (thermogravimetric analysis) of 280°C or more and (D) 0.1 to 1 wt.pts. of a multivalent fatty acid ester (D component) having an acid value of 3 to 15, based on 100 pts.wt. of a resin composition comprising (A) 50 to 90 wt.% of a polycarbonate resin (A component) and 50 to 10 wt.% of a surface hardness improver which is a copolymer having a weight average molecular weight of 5000 to 30000 obtained by copolymerization of (B) (b-1) 10 to 59 wt.% of an aromatic (meth)acrylate monomer (b-1 component), (b-2) 40 to 89 wt.% of an alkyl (meth)acrylate monomer (b-2 component) and (b-3) 1 to 30 wt.% of a modified aromatic vinyl monomer (b-3 component).SELECTED DRAWING: None |
