| Zusammenfassung: | To provide a laminate having low air permeability and excellent moisture permeability in a low temperature and low humidity environment.SOLUTION: The laminate comprises a porous base material, and a moisture permeable film provided on one surface of the porous base material, where an air permeability resistance based on the Gurley method of JIS P8117-2009 is 3,000 seconds/100 cc or more, and a first moisture permeability based on a moisture permeability test method (cup method) of JIS Z0208-1976 under the conditions of a temperature of 5°C, a relative humidity of 45%, and a wind speed of 0.2 m/s is 300 g/(m2 24h) or more.SELECTED DRAWING: Figure 1
【課題】透気性が低く、且つ低温低湿環境下での透湿性に優れる積層体を提供する。【解決手段】多孔質基材と、前記多孔質基材の一方の面に設けられた透湿膜と、を備え、ＪＩＳ Ｐ８１１７−２００９のガーレー法に基づく透気抵抗度が３０００秒／１００ｃｃ以上であり、ＪＩＳ Ｚ０２０８−１９７６の透湿度試験方法（カップ法）に基づく、温度５℃、相対湿度４５％、風速０．２ｍ／ｓ以下の条件における第１透湿度が３００ｇ／（ｍ2・２４ｈ）以上である積層体。【選択図】図１ |
