Abstract
(EN)
Disclosed herein are a security film and a process for preparation thereof. The security film comprises a protective layer (1), a binder layer (2), a retroreflective layer (3), a photopolymerizable information layer (4) and a reflective layer (5) which are combined in turn. The retroreflective layer (3) is embedded spherically in the binder layer (2), and the photopolymerizable information layer (4) has been etched with graphics information which can change along with the viewing angle.

La présente invention concerne un film anticontrefaçon et son procédé de préparation. Ledit film anticontrefaçon est successivement composé d'une couche protectrice (1), d'une couche liante (2), d'une couche rétroréfléchissante (3), d'une couche (4) d'information photopolymérisable et d'une couche réfléchissante (5). Ladite couche rétroréfléchissante (3) est insérée sphériquement dans la couche liante (2). Une information graphique changeant selon l'angle visuel est gravée sur la couche (4) d'information photopolymérisable.
