摘要:
A polyurethane dispersion is obtained by aqueously dispersing an aqueous polyurethane resin obtained by reaction of an isocyanate group-terminated urethane prepolymer with a chain extender. The isocyanate group-terminated urethane prepolymer contains an adhesive urethane prepolymer for imparting adhesion and a gas-barrier urethane prepolymer for imparting gas barrier properties.
