PROBLEM TO BE SOLVED: To provide a card, designed considering its disposal, which exhibits high heat resistance, that is, showing no deformation even at 90 deg.C or higher during deformation tests through setting a sample against a stand at 45 deg. and is free from the generation of a curl and cracks in the embossed card and also hazards such hydrogen chloride and dioxine during incineration after the use of the card. SOLUTION: This card is structured of an amorphous polyethylene terephthalate layer 1, on at least one of the sides of which, sheet layers 2 and 3 composed of an amorphous polyethylene terephthalate and/or a polycarbonate and/or a polyacrylate are laminated. After laminating these layers 1, 2 and 3, a concealing layer 6 and/or a pictorial design-printed layer 7 are laminated by a transfer process. This card is highly heat-resistant, showing no deformation at 90 deg.C or higher. |
