water vapor barrier resin, water vapor barrier coating agent, water vapor barrier film, and water vapor barrier laminate

摘要

The present invention provides a water vapor barrier resin, a water vapor barrier coating agent, a water vapor barrier film, and a water vapor barrier laminate that exhibit higher water vapor barrier properties. The water vapor barrier resin of the present invention is a carboxylic acid of a copolymer (C) obtained by polymerizing an unsaturated hydrocarbon monomer (A) and an unsaturated carboxylic acid and / or an unsaturated dicarboxylic acid anhydride (B). A group and / or an acid anhydride group and an organometallic complex (D) are reacted with each other and have a metal bridge between the copolymers (C). The water vapor barrier coating agent of the present invention contains the water vapor barrier resin of the present invention and a solvent (E). The water vapor barrier film of the present invention is a film containing the water vapor barrier resin of the present invention. The water vapor barrier laminate is obtained by laminating the water vapor barrier film of the present invention on at least one surface of a base film.
