Abstract

Selon un mode de réalisation, la présente invention concerne un tapis de jeu permettant d'effacer les gribouillages comprenant : un tapis inférieur obtenu par un moulage de mousse de polychlorure de vinyle (PVC) ; un adhésif appliqué sur la surface supérieure du tapis inférieur ; une couche d'agent de blocage de plastifiant reliée au tapis inférieur par l'intermédiaire de l'adhésif ; et un tapis supérieur qui est formé sur la surface supérieure de la couche d'agent de blocage de plastifiant, a une couleur spécifique imprimée sur la surface arrière et est obtenu en mélangeant une proportion spécifique de matière inorganique. Ainsi, la présente invention présente l'avantage qu'une couche de revêtement à séchage ultraviolet mat qui contient une proportion spécifique de matière inorganique pour obtenir des propriétés mates et des propriétés d'écriture et d'effacement est formée sur la surface supérieure du tapis de jeu, de telle sorte que les ingrédients des gribouillages réalisés sur la surface supérieure ne puissent pas s'infiltrer, ce qui permet d'effacer les gribouillages à l'aide de tissus humides.
