摘要:
An object of the present invention is to provide a laser-printable laminate display body in which printing is not peeled off even when an external stimulus such as rubbing is applied, and to provide a laminate display body which can afford high-quality laser printing such that characters can be clearly visually recognized by high density and fineness of printing and does not cause defects such as perforation due to laser printing. A laminate display body including at least one printing layer that can undergo printing by laser irradiation, in which the laser printing layer includes a laser-printed portion printed by laser and a non-printed portion, at least one laser non-absorbing layer is laminated on the printing layer, and the absolute value of the difference in color L* value between the laser-printed portion and the non-printed portion is 1.0 or more and 10.0 or less.
