A polyester resin composition according to the present invention includes a polyester polyol having a glycerol skeleton and a curing agent, wherein 5 percent by mass or more of glycerol residue of the polyester polyol is contained in the polyester resin composition. The resin composition can provide an adhesive exhibiting an excellent adhesive force. The adhesive has a gas barrier property or a water vapor barrier property and, therefore, a gas barrier or water vapor barrier film can be provided by using the adhesive.

Polyester resin composition, adhesive and film

The present invention provides a curable resin composition including: a composite resin (A) in which a polysiloxane segment (a1), which has a structural unit represented by a general formula (1) and/or a general formula (2) as well as having a silanol group and/or a hydrolyzable silyl group, and a vinyl-based polymer segment (a2) having an alcoholic hydroxyl group are bound to each other through a bond represented by a general formula (3); and a polyisocyanate (B), wherein the content of said polysiloxane segment (a1) is from 10 to 60% by weight with respect to the total solid content of the curable resin composition, and the content of the polyisocyanate (B) is from 5 to 50% by weight with respect to the total solid content of the curable resin composition.
