Abstract
(EN)
The objective of the present invention is to suppress a deterioration in adhesion, even when silicone migrates from a protective layer side to a heat sealable resin layer side. This in-mold label is provided with a base material layer, a printed layer provided on one surface of the base material layer, and a heat sealable resin layer provided on the other surface of the base material layer, wherein a protective layer containing silicone is provided on an outermost surface on the one surface side of the base material layer on which the printed layer is provided, and an adhesion strength deterioration preventing layer containing a (meth)acrylic acid-based copolymer including a polar group is provided on the outermost surface on the other surface side of the base material layer on which the heat sealable resin layer is provided.

L'objectif de l’invention est de supprimer une détérioration de l'adhérence, même lorsque le silicone migre d'un côté couche de protection à un côté couche de résine thermoscellable. Cette étiquette dans le moule est pourvue d'une couche de matériau de base, d'une couche imprimée disposée sur une surface de la couche de matériau de base, ainsi que d'une couche de résine thermoscellable disposée sur l'autre surface de la couche de matériau de base, une couche de protection contenant du silicone étant disposée sur une surface la plus externe du côté de surface de la couche de matériau de base sur laquelle est disposée la couche imprimée, et une couche de prévention de dégradation de force d'adhérence contenant un copolymère à base d’acide (méth)acrylique comprenant un groupe polaire est disposée sur la surface la plus externe de l'autre côté de surface de la couche de matériau de base sur laquelle est disposée la couche de résine thermoscellable.
