A resin composition is provided. The resin composition comprises an epoxy resin and a hardener, wherein the amount of the hardener is about 10 parts by weight to about 200 parts by weight per 100 parts by weight of the epoxy resin and the hardener comprises a first styrene-maleic anhydride copolymer (SMA) copolymer and a second SMA copolymer, the first SMA copolymer has a molar ratio of styrene to maleic anhydride m1, the second SMA copolymer has a molar ratio of styrene to maleic anhydride m2, and m1−m2≧3. |
