Zusammenfassung: | Disclosed is a method for manufacturing a multilayer data medium (1), in which method: a multilayer data medium, including at least one transparent security layer (16), and at least one marking layer (17), sensitive to electromagnetic-marking radiation (5), are selected; the transparent security layer (16) includes at least one semi-transparent printed image including at least one thermochromic dye; at least one marking (30) is made using the electromagnetic-marking radiation, through the printed image; the semi-transparent printed image reveals, in a first state referred to as the inactivated state, at least one semi-transparent visible pattern that makes it possible, after the marking step, to view the marking (30) through the image, the pattern not being visible in a second state, referred to as the activated state. The invention also relates to a multilayer data medium (1). |
