Title:
LAMINATE
Document Type and Number:
WIPO Patent Application WO/2022/070948
Kind Code:
A1
Abstract:
Provided is a laminate that has low air permeability and excellent moisture permeability. A laminate 1 is provided with a porous base material 11 and a moisture permeable film 12 that is provided on at least one surface 11a of the porous base material 11. The moisture permeable film 12 is formed of a resin in which, when a negative integral value is an attraction value relative to water and a positive integral value is a repulsive value relative to water, the attraction value is -110 kcal/mol or less and the repulsive value is 35 kcal/mol or more in an energy histogram of a combination of a solute and a solvent obtained from a process of calculating free energy based on energy representation.
