摘要

The present invention relates to a polyurethane laminating adhesives, methods for producing a multilayer laminate by laminating at least two films with a polyurethane laminating adhesive, and multilayer laminates obtainable by these methods wherein the polyurethane laminating adhesive comprises an NCO-terminated polyurethane prepolymer obtainable by reacting a polyol mixture comprising: 0.1 to 20.0 wt % relative to the total weight of the polyol mixture of at least one polybutadiene polyol; and 5.0 to 99.9 wt % relative to the total weight of the polyol mixture of at least one polyether polyol, wherein the at least one polyether polyol comprises at least one polyether polyol with a number average molecular weight Mn in the range of 1000 g/mol to 10000 g/mol; with at least one polyisocyanate, wherein the at least one polyisocyanate is used in an amount such that the isocyanate groups are present in molar excess relative to the hydroxyl groups of the polyol mixture. Also encompassed are the use of the described adhesives for laminating two or more films, and the multilayer laminates obtainable by the described methods.
