Patent

CA 2293807

A card (5) is disclosed that incorporates a removable scratch-off coating (40) to hide printed symbols. The card is constructed so that the scratch-off coating is selectively retained by the card, in the form of symbols, or as a background for symbols, when the scratch-off coating is removed. The selective retention of scratch-off coating materials to the card is accomplished by incorporating into the card, between the substrate (10) and the scratch-off coating, a clear release coat (30) patterned to form symbols. When the scratch- off coating material is applied to the card during construction, it either adheres directly to the substrate in the form of symbols, or it adheres to the substrate in the background for the symbols, depending on how the release coat is applied. When a player rubs the scratch-off coating material, it releases from the release coat and remains adhered to the substrate to create either symbols or the background for symbols.

La présente invention concerne une carte (5) comporte un couche (40) s'éliminant au grattage destinée à cacher des symboles imprimés. La carte est fabriquée de manière que la couche de grattage soit sélectivement retenue sur la carte, laissant apparaître soit des symboles, soit un fond comportant des symboles lorsque la couche de grattage est éliminée. L'adhésion sélective des matériaux de la couche de grattage à la carte est obtenue par incorporation à la carte, entre le substrat (10) et la couche de grattage, d'une couche de séparation transparente (30) portant des motifs destinés à former des symboles. Lorsque le matériau est appliqué sur la carte pendant la fabrication, il est amené soit à adhérer directement sur le substrat pour former des symboles, soit à adhérer sur le substrat pour former le fond sur lequel sont représentés les symboles, en fonction du mode choisi pour appliquer la couche de séparation. Lorsqu'un joueur gratte la couche de grattage, celle-ci se détache de la couche de séparation et reste collée au substrat de manière à former soit les symboles, soit le fond.
