Zusammenfassung:To solve the problem that conventional polyurethane resins are not intended for resources conservation and environmental load reduction, and the problem that it is unknown whether it can be processed into a laminate adhesive when using a plant-derived raw material.SOLUTION: A two-component laminate adhesive includes a biomass polyester polyol whose acid component and/or glycol component is a biomass component, and an isocyanate compound.SELECTED DRAWING: None 【課題】従来のポリウレタン樹脂は、資源の保全及び環境負荷低減に資するものではなく、また植物由来の原料を用いた場合、ラミネート接着にすることまで可能であるのかも不明であった。【解決手段】酸成分及び/又はグリコール成分がバイオマス成分であるバイオマスポリエステルポリオール及びイソシアネート化合物を含有する2液型ラミネート接着剤。【選択図】なし
