FIELD: adhesive materials.

SUBSTANCE: invention relates to two-component adhesive compositions which do not contain a solvent, a method of producing a laminate, involving use of such compositions, and a laminate obtained using said method. Solvent-free two-component adhesive composition contains an isocyanate component containing an isocyanate prepolymer which is a reaction product of reagents containing at least one polyisocyanate; and at least one polyol having two or more OH groups and a hydrogen bonding group; and a polyol component containing at least one polyol selected from the group consisting of polyester polyol, polyether polyol and combinations thereof. Method of laminate production includes production of solvent-free two-component adhesive composition, applying a layer of said composition on the surface of the film, bringing said layer into contact with the surface of the other film to obtain a laminate and curing the adhesive composition. Laminate made according to said method is also disclosed.

EFFECT: technical result is obtaining compositions with improved gluing strength, chemical resistance and strength of thermal seam.
