FIELD: chemistry.
SUBSTANCE: invention relates to a process for producing laminated structures by using two-component polyurethane compositions. Method for producing laminated structures comprises bringing component A into contact with component B to form an adhesive composition, forming a layer of said adhesive composition on the surface of a first film, and bringing the surface of a second film into contact with said layer of adhesive composition, wherein component A of the adhesive composition is one or more polyisocyanates and component B of the adhesive composition is one or more hybrid polyols containing reaction residues of the initiating polyol containing N hydroxy groups, where N is 2 or more, and the number average molecular weight of the initiating polyol is 900 or less, one or more anhydrides and two or more alkylene oxides. Adhesive composition of the invention is intended to be used as a two-component adhesive for lamination.
EFFECT: laminated structures obtained by this method have improved adhesion characteristics.
