Flame-retardant scratch-resistant thermoplastic resin composition with improved compatibility

A flame-retardant scratch-resistant thermoplastic resin composition comprising:

• a base resin comprising (A) about 20 to about 95% by weight of a polycarbonate resin;
• (B) about 1 to about 50% by weight of a copolymer resin comprising (B1) about 0 to about 100% by weight of a rubber modified vinyl graft copolymer resin and (B2) about 0 to about 100% by weight of a vinyl copolymer resin;
• and (C) about 1 to about 50% by weight of a (meth)acrylic copolymer resin with a refractive index of about 1.50 to about 1.59, wherein said (meth)acrylic copolymer resin (C) is a copolymer consisting of (c1) about 50 to about 90% by weight of an aromatic methacrylate, an aliphatic methacrylate, or a mixture thereof represented by the following Chemical Formula 1, Chemical Formula 2, or a mixture thereof and (c2) about 10 to about 50% by weight of a mono-functional unsaturated monomer selected from the group consisting of methacrylic acid ester monomers;
• acrylic acid ester monomers;
• unsaturated carboxylic acid monomers;
• acid anhydride monomers;
• hydroxyl group containing ester monomers;
• amide monomers;
• nitrile monomers;
• allyl glycidyl ethers;
• glycidyl methacrylates;
• and mixtures thereof:
• wherein m is an integer from 0 to 10, and X is a cyclohexyl group, a phenyl group, a methylphenyl group, a methylethylphenyl group, a methoxyphenyl group, a cyclohexylphenyl group, a chlorophenyl group, a bromophenyl group, a phenylphenyl group, or a benzylphenyl group;
• wherein m is an integer from 0 to 10, Y is oxygen (O) or sulfur (S), and Ar is a cyclohexyl group, a phenyl group, a methylphenyl group, a methylethylphenyl group, a methoxyphenyl group, a cyclohexylphenyl group, a chlorophenyl group, a bromophenyl group, a phenylphenyl group, or a benzylphenyl group, and
• (D) about 0.1 to about 40 parts by weight of a flame retardant, per 100 parts by weight of a base resin comprising (A)+(B)+(C).
