PROBLEM TO BE SOLVED: To suppress generation of a hydrogen chloride or the like when incinerated and discarded by arranging print layers each containing a predetermined alloy and a pigment as main components on both surfaces of a sheet-like base material of an amorphous polyester of a copolymer of a terephthalic acid, a cyclohexanedimethanol and an ethylene glycol. SOLUTION: Print layers 2 each containing an alloy (alloy A) of an amorphous polyester and a polycarbonate and a pigment as main components are provided on both surfaces of a sheet-like base material 1 of an amorphous polyester of a copolymer of a terephthalic acid, a cyclohexanedimethanol and an ethylene glycol, and a sheet 3 of an amorphous polyester is further arranged to form the card. The polyester for constituting the alloy A is an amorphous polyester resin PETG, a glass transition temperature of which can be controlled by changing a blending ratio of the cyclohexanedimethanol and the ethylene glycol. |
