COMPOSITION FOR ADHESIVE, AND LAMINATE

WIPO Patent Application WO/2023/047872

A1

Provided is a composition for adhesives which gives an adhesive with which a metal foil and a resinous film can be tenaciously bonded to each other even at high temperatures. The composition for adhesives comprises: an acid-modified polyolefin (component 1); a polyisocyanate compound (component 2) which is a compound comprising a framework and p (p is an integer of 2 or lager) isocyanato groups bonded thereto; a modified isocyanate compound (component 3) which is a compound comprising a framework having the same structure as that of the polyisocyanate compound of component 2 and, bonded thereto, q (q is an integer of 1 or lager) isocyanato group(s) and r (r is an integer of 1 or larger and satisfies q+r=p) modifying group(s); a reaction catalyst (component 4); and a solvent (component 5). When the total number of moles of the isocyanato groups contained in component 2, the total number of moles of the isocyanato groups contained in component 3, and the total number of moles of the modifying groups contained in component 3 are respectively expressed by Ia, Ib, and H, then the ratio of H to the sum of Ia, Ib, and H, H/(Ia+Ib+H), is larger than 0 but not larger than 0.5.
