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 une zone à gratter. Un film à gratter est appliqué sur la zone à gratter. Une matière de finition est appliquée sur le film à gratter. La matière de finition est préparée avec un réactif qui réagit avec des substances chimiques utilisées pour une tentative de soulèvement mécanique assisté du SOC, et permet d'obtenir une indication visuelle indiquant l'utilisation de telles substances chimiques lors d'une tentative de manipulation frauduleuse du SOC visant à discerner des indices ou images situé(e)s sous le SOC.
