Document Type and Number:
WIPO Patent Application WO/2020/075713
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a microporous film having permanent hydrophilicity but free of clogging of fine pores caused during hydrophilization of the microporous film. A means was discovered for hydrophilization of a microporous film without hindering the water permeability of the microporous film, and the means involves coating a microporous film with a hydrophilic monomer and a crosslinking-agent monomer as a combination or each singly. The present invention provides: a coating composition that is for hydrophilization of a microporous film and that contains a trifunctional acrylate compound and a salt of an acrylamide monomer compound: and a hydrophilic microporous film coated with a polymer derived from said coating composition.
