Abstract
(EN) The article includes a microporous thermoplastic film having first and second major surfaces and having an opaque, microporous region and a see-through region of lower porosity having a pre-determined shape. The article further includes a first adhesive having a first color disposed on the second major surface of the microporous thermoplastic film, wherein a portion of the first adhesive is visible through the see-through region of lower porosity when viewed from the first major surface of the microporous thermoplastic film. The article may include multiple adhesives with multiple colors. A method of making the article is also described.
(FR) La présente invention concerne un article comprenant un film thermoplastique microporeux ayant une première et une seconde surface majeure et ayant une région microporeuse opaque, et une région traversante de porosité inférieure ayant une forme prédéterminée. L'article comprend en outre un premier adhésif ayant une première couleur disposée sur la seconde surface majeure du film thermoplastique microporeux, une portion du premier adhésif étant visible à travers la région traversante de porosité inférieure lorsque visualisée depuis la première surface majeure du film thermoplastique microporeux. L'article peut comprendre de multiples adhésifs ayant de multiples couleurs. L'invention concerne également un procédé de fabrication de l'article.
