Zusammenfassung:To provide a resin composition for cards or passports that has improved low-temperature fusibility, thermostability, and solvent resistance, while having improved laser printability.SOLUTION: A resin composition for cards or passports contains a resin component containing a polyester resin (A) and a colorant. The polyester resin (A) contains a constitutional unit derived from an open-chain dihydroxy compound. The polyester resin (A) has a glass transition temperature of 90°C or higher.SELECTED DRAWING: None 【課題】低温融着性、耐熱性、耐溶剤性を良好にしながら、レーザー印字性も良好にできるカード又はパスポート用の樹脂組成物を提供する。【解決手段】カード又はパスポート用樹脂組成物は、ポリエステル樹脂(A)を含む樹脂成分と着色剤とを含有する樹脂組成物であって、該ポリエステル樹脂(A)が鎖式ジヒドロキシ化合物に由来する構造単位を含み、該ポリエステル樹脂(A)のガラス転移温度が90℃以上である。【選択図】なし
