Abstract

L'invention concerne un procédé (et un substrat associé) permettant d'empêcher et de détecter le retrait frauduleux d'un film à gratter (SOC) d'un substrat présentant au moins une zone à gratter. Une couche détachable est appliquée sur la zone à gratter, et un film à gratter est appliqué sur la couche détachable. La couche détachable est modifiée de manière à présenter des propriétés de libération non uniformes sur la zone à gratter de sorte que le film à gratter ne peut pas être soulevé, ni retiré, comme une couche continue, de telle sorte que les indices ou images sous-jacent(e)s situé(e)s dans la zone à gratter restent visuellement discernables lors du retrait du film à gratter dans un processus de retrait voulu normal, par exemple lors d'un grattage du SOC à l'aide d'une pièce de monnaie, d'un ongle etc.
