    Abstract: The present invention relates to a process for producing a polyurethane lamination resin, by mixing a) an isocyanate prepolymer based on diphenylmethane diisocyanate having a difunctionally started polyether, b) polyphenylene polymethylene polyisocyanate, c) trifunctionally started polyetherpolyol with an average molar mass of from 350 to 600 g/mol, d) a thermoactivatable capped catalyst, e) if appropriate, chain extender and/or crosslinking agent, f) if appropriate, water-absorbent substances, and g) if appropriate, other additives to give the polyurethane lamination resin. The present invention further relates to a polyurethane lamination resin, obtainable via a process of this type, and to the use of this type of polyurethane lamination resin for producing laminates, and also to skis or snowboards, comprising this type of laminate.
