摘要:
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.
