摘要 |
<p>PROBLEM TO BE SOLVED: To provide a multilayered polyester sheet used in a card such as a magnetic card or an IC card excellent not only in embossing processability but also in heat resistance and impact resistance, and the card comprising the same. SOLUTION: The multilayered polyester sheet is formed by laminating two or more sheets. At least one layer thereof is a sheet A comprising a thermoplastic resin composition prepared by compounding (a) amorphous polyester and (b) aromatic polycarbonate so that a weight ratio (a)/(b) becomes 10/90-80/20, and at least one layer thereof is a sheet B comprising a thermoplastic resin composition prepared by compounding 2-25 pts.wt. of (c) an inorganic lamellar filler with 100 pts.wt. of a thermoplastic resin component. A weight ratio (a)/(b) of (a) amorphous polyester and (b) aromatic polycarbonate is 85/15-100/0.</p> |
