MOISTURE-RESISTANT COMPOSITE SHEET THAT COMPRISES BASE SHEET LAYER COMPRISING FINE FIBER AND INORGANIC LAYER

摘要

PROBLEM TO BE SOLVED: To prevent a dimensional change in a high-temperature high-humidity environment of a sheet comprising a fine fiber to which a substituent having an electrostatic and/or three-dimensional functionality is introduced.SOLUTION: A composite sheet comprises a base sheet layer comprising a fine fiber (preferably, a fine fiber to which a substituent having an electrostatic and/or three-dimensional functionality is introduced), and an inorganic layer formed on at least one side of the base sheet layer. At least one side of the base sheet layer may further have an organic layer.SELECTED DRAWING: None
