Abstract

L'invention concerne un article fonctionnel ayant une couche fonctionnelle et une couche adhésive et conçu pour, tout en conservant l'effet de la couche fonctionnelle, empêcher la couche adhésive de rester sur la peau ou le sous-vêtement d'un utilisateur lors de l'enlèvement de l'article fonctionnel. Un article fonctionnel (1) comprend des matériaux de base (7, 9) et une couche adhésive (21) formée sur une surface de contact avec la peau ou une surface de contact avec non-peau des matériaux de base. L'article fonctionnel comprend une couche fonctionnelle (13) ayant une fonction prédéterminée et disposée plus près de la surface de contact avec la peau des matériaux de base que la surface de contact avec non-peau de ces derniers et le long de la surface de contact avec la peau. La couche fonctionnelle a un agent fonctionnel contenant un composant lipophile. La couche fonctionnelle et la couche adhésive sont formées de telle sorte qu'au moins une partie de la couche fonctionnelle ne chevauche pas la couche adhésive dans une direction de l'épaisseur de l'article fonctionnel et qu'au moins une partie de la couche adhésive ne chevauche pas la couche fonctionnelle dans la direction de l'épaisseur de l'article fonctionnel.
