Title
(EN) RELEASE SHEET
(FR) FEUILLE ANTI-ADHÉSIVE
(JA) 剥離シート
Abstract
(EN) Provided is a release sheet which allows manufacture of an adhesive sheet which can easily be adhered in a manner in which air bubbles do not form between the adhesive sheet and the adherend. In this release sheet (RL), in which one contact surface (RA) is temporarily adhered to an adhesive sheet (AS), the one contact surface (RA) has a first depression (HL) which includes one first punctate deepest portion (DP) and which at any position separated from the first punctate deepest portion (DP), is deeper towards the first punctate deepest portion (DP) than towards the outer edge (EG). The first depression (HL) is provided so as to allow forming, on an adhesive (AD) layer of the one adhesion sheet (AS), one first top point (TP) which can make point contact with the adherend.
(FR) La présente invention se rapporte à une feuille anti-adhésive qui permet la fabrication d'une feuille adhésive qui peut être facilement collée de sorte que des bulles d'air ne se forment pas entre la feuille adhésive et la surface à coller. Dans cette feuille anti-adhésive (RL), dans laquelle une surface de contact (RA) est temporairement collée sur une feuille adhésive (AS), la surface de contact (RA) présente une première dépression (HL) qui comprend une première partie ponctuée la plus profonde (DP) et qui est plus profonde, à n'importe quelle position distincte de la première partie ponctuée la plus profonde (DP), vers la première partie ponctuée la plus profonde (DP) que vers le bord externe (EG). La première dépression (HL) est disposée de façon à permettre la formation, sur une couche adhésive (AD) de la feuille adhésive (AS), d'un premier point supérieur (TP) qui peut constituer un point de contact avec la surface à coller.
(JA)  簡単に被着体との間に気泡が形成されないように貼付することができる接着シートを製造可能な剥離シートを提供すること。 接着シート(AS)に一方の当接面(RA)が仮着される剥離シート(RL)において、一方の当接面(RA)は、点状の1の最深部である第1点状最深部(DP)から離間したいずれの位置においても当該第1点状最深部(DP)側が外縁(EG)側に比べて深く設けられた第1凹部(HL)を有し、第1凹部(HL)は、被着体に点接触可能な1の第1頂点(TP)を1の接着シート(AS)の接着剤(AD)層に形成可能に設られている。
