To provide a card having an excellent abrasion resisting property on the surface of the card by not making the looking of appearance worse while maintaining its superior heat resistance.
The card is of a three-layer construction of a transparent upper sheet 1, a center core sheet 2, and a transparent lower sheet 3. The material of the center core sheet 2 is the resin composition of a uniform mixture of chlorine vinyl chloride as a first component, a methacrylic acid ester-butadiene- stylene copolymer as a second component, and a rubber-nitrile monomer-stylene copolymer as a third component. A printing layer 4 is formed on the upper surface of the center core sheet 2. The center core sheet 2 consisting mainly of chlorine vinyl chloride has good heat resistance. Also, the printing layer 4 is protected by the transparent upper sheet 1 and lower sheet 3.
