(57) [Summary] [Structure] A flexible substrate, at least one of which is a polystyrene film, is reacted with an organic polyol containing polytetramethylene glycol as an essential polyol component, an organic polyisocyanate, and a polyamine compound such as isophoronediamine. A laminate obtained by laminating with a two-component curable adhesive composition containing a polyurethane resin (a) in which at least one of the molecular ends is an amino group and an epoxy compound (b) having at least two glycidyl groups in the molecule Method. [Effect] Since it has excellent adhesiveness, particularly adhesiveness to a polystyrene resin substrate, it is possible to manufacture various composite packaging materials without peeling. |
