Abstract: There is provided an over-sheet for a card, the sheet being formed of at least three layers including a skin layer and a core layer and laminated by a coextrusion technique. The skin layer, which is an outermost layer on both sides of the three-layer sheet, is formed of a substantially amorphous aromatic polyester-based resin composition containing 0.01 to 3 parts by mass of at least one lubricant selected from the group of fatty acid ester, fatty acid amide, and fatty acid metal salt. The core layer is formed of a polycarbonate resin.

Abstract: A laser marking multilayer sheet includes a multilayer sheet A, and a multilayer sheet B that is stacked under the multilayer sheet A. The multilayer sheet A is a transparent laser marking multilayer sheet. A skin layer that forms each outermost layer of the multilayer sheet A is formed of a noncrystalline aromatic polyester resin composition, and a core layer of the multilayer sheet A is formed of a polycarbonate resin composition. The multilayer sheet B is a colored laser marking multilayer sheet. A skin layer that forms each outermost layer of the multilayer sheet B is formed of a noncrystalline aromatic polyester resin composition, and a core layer of the multilayer sheet B is formed of a polycarbonate resin composition.

Abstract: There is provided a laser-marking multilayer sheet for an electronic passport formed by laminating five sheets of a multilayer sheet A/a multilayer sheet B/a film C/a multilayer sheet B/a multilayer sheet A. The multilayer sheet B is a colored laser-marking multilayer sheet. The film C is a laser-marking multilayer sheet made of a film for the electronic passport. The laser-marking multilayer sheet can have clear letters, symbols, and images, which are excellent in a laser-marking property and high in contrasts between the original surface color and the printed portions. The laser-marking multilayer sheet is excellent especially for inhibiting the falsification and forgery thereof.

Abstract: Disclosed is a composite hinge sheet including thermoplastic resin layers 5 made of a thermoplastic resin formed on both surfaces of a woven-fabric like sheet 3 having multiple openings therein. The woven-fabric like sheet 3 includes woven fabric or non-woven fabric made of at least one type selected from polyester, polyamide and polypropylene. The thermoplastic resin layers 5 include, as a raw material, resin having Shore A surface hardness flexibility of 85 or greater and Shore D surface hardness flexibility of less than 70. A part of the thermoplastic resin enters the openings in the woven-fabric like sheet 5, thus blocking all the openings, so that the thermoplastic resin layers 5 are integrated with the woven-fabric like sheet 3. The composite hinge sheet has excellent tearing and tensile strength, is resistant to light and heat in the binding part thereof, and has excellent resistance to repeated bending.

Abstract: A multilayer laser-markable sheet for an electronic passport includes three sheets of a sheet A/a multilayer sheet B/a sheet C as a basic constitutional unit. The sheet A includes a transparent polycarbonate resin composition including a thermoplastic polycarbonate resin and a laser light energy absorbing agent, the multilayer sheet B includes a transparent thermoplastic resin including a thermoplastic polycarbonate resin, at least one layer of the skin layers and the core layer of the multilayer sheet B including at least one selected from a dye and a pigment. The sheet C includes a sheet or a laminate sheet. The multilayer laser-markable sheet for an electronic passport has excellent laser markability and high contrast, can achieve clear letters, symbols and images, and further has excellent thermal adhesiveness, transparency, sheet conveyance property, releasability from a die after thermal press, thermal resistance, foldability and wear resistance.
