Claim:
1. A touch panel, comprising: a first conductive plastic film; a second conductive plastic film, an adhesive film disposed between the first conductive plastic film and the second conductive plastic film, wherein the first adhesive layer has a thickness of 1 μm to 50 μm, wherein the second adhesive layer has a thickness of 10 μm to 250 μm, wherein the first acrylic resin is prepared by putting 65 parts by weight of ethylhexyl acrylate (EHA), 25 parts by weight of methyl acrylate (MA), and 10 parts by weight of hydroxybutyl acrylate (HBA) into a first 1 L reactor equipped with a reflux condenser, adding ethyl acetate (EAc) as a solvent, stirring, after oxygen was purged from the reactor with nitrogen gas for 1 hour, the mixture while maintaining temperature at 62° C., adding 0.03 parts by weight of azobisisobutyronitrile (AIBN) diluted with ethyl acetate to 50% as a reaction initiator, and reacting the mixture for about 8 hours, and wherein the second adhesive layer comprises a second acrylic resin which is prepared by putting 90 parts by weight of ethylhexyl acrylate (EHA) and 10 parts by weight acrylic acid (AA) into the first 1 L reactor or a second 1 L reactor equipped with a reflux condenser, adding ethyl acetate (EAc) as a solvent, stirring, after oxygen was purged from the reactor with nitrogen gas for 1 hour, the mixture while maintaining temperature at 62° C., adding 0.03 parts by weight of azobisisobutyronitrile (AIBN) diluted with ethyl acetate to 50% as a reaction initiator, and reacting the mixture for about 8 hours.
