Water dispersion of a polyhydroxyurethane resin, the manufacturing method of this water dispersion, the gas barrier resin film which uses this water dispersion, the polyhydroxyurethane resin water dispersion composition containing clay mineral, and the gas barrier using this composition Coating agent and gas barrier resin film

摘要

Providing the water dispersion of the polyhydroxyurethane resin which can form the film | membrane which is excellent in gas barrier property which can be preserve | required industrially for a long time, The water dispersion composition which combined this resin and the clay mineral, The gas barrier property using these Offer of this excellent film. Specifically, the chemical structural site | part which has the repeating unit represented by Formula (1) in which the polyhydroxyurethane resin is undispersed in water as a basic structure, and has a carboxyl group represented by Formula (6) in this structure. The water dispersion of the polyhydroxyurethane resin which has the thing, the water dispersion composition which this polyhydroxyurethane resin component and layered clay mineral were composite | combined favorably, and provision of the gas barrier resin film which uses these is provided.
