To provide an adhesive sheet, which can maintain the dirt resistance for a long period of time and does not cause deterioration of the flexibility of the whole adhesive sheet. The adhesive sheet comprises a flexible substrate, an adhesive layer provided on the back surface of the flexible substrate, and a protective layer provided on the front surface of the flexible substrate, characterized in that: the protective layer is a thermoplastic resin layer containing (a) a fluorine copolymer, (b) a non-fluorine polymer, and (c) a hydrophilic agent.
L'invention concerne une feuille adhésive capable de conserver pendant une longue durée une résistance à l'encrassement sans altérer la souplesse de la feuille adhésive dans son ensemble. La feuille adhésive comporte un substrat souple, une couche adhésive située sur le dos du substrat souple, et une couche de protection située sur la face antérieure du substrat souple. Elle est caractérisée par le fait que la couche de protection est une couche de résine thermoplastique contenant (a) un copolymère fluoré, (b) un polymère non fluoré, et (c) un agent hydrophile.
