Patent ID: 8642693

Claim:
A scratch-resistant flameproof thermoplastic resin composition, the resin composition comprising: a base resin comprising (A) about 50 to about 90% by weight of a polycarbonate resin; (B) about 1 to about 50% by weight of a methacrylic copolymer resin with a refractive index of about 1.495 to about 1.590, wherein said methacrylic copolymer resin is a copolymer consisting of (b1) about 70 to about 90% by weight of an aromatic methacrylate, an aliphatic methacrylate, or a combination thereof represented by the following Chemical Formula 1, Chemical Formula 2, or a combination thereof; and (b2) about 10 to about 30% by weight of a mono-functional unsaturated monomer, wherein said mono-functional unsaturated monomer is a methacrylic acid ester monomer; acrylic acid ester monomer; unsaturated carboxylic acid monomer; acid anhydride monomer; hydroxyl group containing ester monomer; (meth)acrylamide monomer; unsaturated nitrile monomer; allyl glycidyl ether; glycidyl methacrylate; or a combination thereof: wherein m is an integer from 0 to 10, and X comprises a cyclohexyl group, a phenyl group, a methylphenyl group, a methylethylphenyl group, a propylphenyl 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 comprises 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 (C) about 0 to about 49% by weight of a (meth)acrylic resin; and (D) about 5 to about 40 parts by weight of a flame retardant, based on about 100 parts by weight of the base resin including (A)+(B)+(C).
