PURPOSE: To obtain an optical card which prevents a crack from being generated by a method wherein a hard coating layer is composed of a UV-curing resin and of a resin composition which contains a ternary copolymer of ethylene, acrylate and maleic acid anhydride. CONSTITUTION: A polycarbonate resin or a polyolefin resin which is flexible is used as a transparent substrate which uses a hard coating layer 11 for an optical card, and especially the polycarbonate resin is suitable. In this case, when a ternary copolymer of ethylene, acrylate and maleic acid anhydride which is flexible is added to a UV-curing resin, the bend-resistant property of the hard coating layer 11 is enhanced. As a result, even when the thickness of the hard coating layer 11 is set at 6μm or higher, a crack is not generated in the hard coating layer 11 when the bending property of the optical card is tested. |
