Abstract

L'invention concerne une couche jetable comprenant : une région avant, qui est une section d'encerclement de taille avant qui a le centre de la direction de longueur de produit comme référence, et qui est plus proche du centre de la direction de longueur de produit qu'une région cible ; des régions colorées visibles qui sont situées dans la région avant ; et une région blanche qui est plus proche de la peau du porteur que la région avant, et qui permet à la couleur de la peau du porteur d'apparaître à travers cette dernière dans une proportion spécifiée. Lorsque les régions colorées sont divisées en premières régions, qui sont colorées avec une couleur spécifiée dans le catalogue d'échantillons de couleurs PANTONE (marque déposée), et en secondes régions qui sont colorées avec une autre couleur, la zone des premières régions est plus grande que la zone des secondes régions.
