Abstract:
(EN) The purpose of the present invention is to provide a laminate of a porous layer and an adhesive layer, wherein the laminate both has pressure-sensitive adhesiveness or adhesiveness and is difficult for a pressure-sensitive adhesive agent or adhesive agent to infiltrate into pores. In order to achieve the above purpose, a first laminate of the present invention is characterized by including a porous layer (20) and an adhesive layer (30), wherein: the adhesive layer (30) is directly laminated on one surface or both surfaces of the porous layer (20); the porosity of the porous layer (20) is at least 35 vol%; and the residual porosity of the porous layer (20) after performing a heating and humidifying durability test in which the porous layer (20) is maintained for 500 h at a temperature of 85°C and a relative humidity of 85% is at least 50 vol% of the porosity of the porous layer (20) before the heating and humidifying durability test.
(FR) La présente invention concerne un stratifié d’une couche poreuse et d’une couche adhésive, le stratifié ayant à la fois une adhésivité sensible à la pression ou une capacité d’adhésion et il est difficile pour un agent adhésif sensible à la pression ou un agent adhésif de s’infiltrer dans ses pores. Afin d’atteindre le but ci-dessus, un premier stratifié de la présente invention est caractérisé en ce qu’il comprend une couche poreuse (20) et une couche adhésive (30), la couche adhésive (30) étant directement stratifiée sur une surface ou les deux surfaces de la couche poreuse (20) ; la porosité de la couche poreuse (20) est d’au moins 35 % en volume ; et la porosité résiduelle de la couche poreuse (20) après réalisation d’un chauffage et d’un test de durabilité à l’humidification dans lequel la couche poreuse (20) est maintenue durant 500 h à une température de 85 °C et une humidité relative de 85 % est d’au moins 50 % en volume de la porosité de la couche poreuse (20) avant le chauffage et le test de durabilité à l’humidification.
(JA) 本発明は、本発明は、粘着力または接着力と、空隙への粘着剤または接着剤の浸透しにくさとを両立した、空隙層と粘接着層との積層体の提供を目的とする。 前記目的を達成するために、本発明の第1の積層体は、 空隙層(20)と、粘接着層(30)とを含み、 粘接着層(30)が、空隙層(20)の片面または両面に直接積層され、 空隙層(20)の空隙率が、35体積%以上であり、 温度85℃かつ相対湿度85%で500h保持する加熱加湿耐久性試験後に、空隙層(20)の空隙残存率が、前記加熱加湿耐久性試験前の50体積%以上であることを特徴とする。
