<p>The present invention addresses the problem of providing a two-pack curable adhesive composition for laminating which can be applied even when having a nonvolatile content of 50 mass% or higher and which has excellent laminating properties. The adhesive composition causes no problem of delamination, etc. when the laminate is subjected to high-temperature sterilization such as boiling or retortion. The two-pack curable adhesive composition for laminating comprises a polyester polyol ingredient as the main component and a polyisocyanate ingredient as a hardener, and is characterized in that the polyester polyol ingredient as the main component was obtained using a polycarboxylic acid or polycarboxylic acid anhydride that contained aromatic rings derived from the orthophthalic acid or phthalic anhydride (OPA) used as a starting material, in an amount of 2.0 mmol or more per g of the solid matter, and that the polyester polyol as the main component has a number-average molecular weight of 4,000 or lower.</p> |
