POLYESTER RESIN COMPOSITION, ADHESIVE, AND FILM

摘要

The present invention is a polyester resin composition containing a polyester polyol with a glycerol backbone, and a curing agent. The polyester resin composition is characterized by containing at least 5 mass% of the glycerol backbone of the polyester polyol. The resin composition enables an adhesive with excellent adhesive strength to be provided. The adhesive acts has gas barrier and vapor barrier properties, and can therefore be used to provide a film with gas barrier and vapor barrier properties.
