Beschreibung
Zusammenfassung:	An adhesive for laminates comprising as the main component an epoxy resin composition composed of an epoxy resin and an epoxy-curing agent, wherein the skeletal structure of formula (1) is contained in the cured article of the epoxy resin composition in an amount of 40 wt% or above. Since the adhesive exhibits both favorable adhesiveness to various film materials and high gas barrier properties, a layer having both gas barrier properties and adhesiveness can be formed from the adhesive, which makes it possible to produce packaging film laminates having high gas barrier properties without forming a gas barrier layer separately.
