Lamination method

A method of forming a laminated structure comprising

• I bringing a component A into contact with a component B to form an adhesive composition,
• II forming a layer of said adhesive composition on one surface of a first film, and
• III bringing the surface of a second film into contact with said layer of adhesive composition;
• wherein said component A comprises one or more polyisocyanate, and wherein said component B comprises one or more hybrid polyol comprising reaction residues of
• (i). one initiator polyol having N hydroxyl groups, wherein N is 2 or greater, and wherein the number-average molecular weight of said initiator polyol is 900 or lower,
• (ii). one or more anhydride, and
• (iii). two or more alkylene oxides having the structure
• wherein said R3 is hydrogen or an alkyl group,
• wherein the mole ratio of said reaction residues of anhydride to said reaction residues of initiator polyol is N:1 or less.
