摘要：A moisture-curing composition bad on isocyanate group-containing polyurethane prepolymer(s) also contains at least one polyaldimine derived from a di-, tri- or tetra-functional polyamine and a 2,2-disubstituted 3-(11-30C alkoxy)- or 3-(acyloxy)-propionaldehyde. Moisture-curing compositions (MCC) containing (a) isocyanate group-containing polyurethane prepolymer(s) (P), (b) polyaldimine(s) (ALD) of formula (I) and optionally (c) an oligomeric polyisocyanate (OP). X : the residue of an n-functional polyamine with a mol. wt. of not more than 300 g/mol after removing all NH 2 groups, this residue having no groups which can react with isocyanate in the abnce of water, especially no hydroxyl, c. amino, urea or other groups with reactive hydrogen; n : 2, 3 or 4; R 1>, R 2>1-12C hydrocarbyl, or combined to form a 4-20C hydrocarbylene residue forming part of an optionally substituted carbocyclic ring with 5-8 (preferably 6) atoms; R 3>H, alkyl or arylalkyl; R 4>11-30C hydrocarbyl (optionally with hetero-atoms) or a group of formula ---CO-R 5> (II); R 5>11-30C alkyl (optionally with cyclic components and optionally with hetero-atom(s), preferably oxygen in

the form of ether, ester or aldehyde groups), 11-30C mono- or poly-unsaturated hydrocarbyl, or an optionally substituted
aromatic or heteroaromatic 5- or 6-membered ring . The content of ALD (I) is at least 22 wt% bad on all isocyanate group-containing components. Independent claims are also included for (1) hardened compositions obtained by reacting MCC with water, especially atmospheric moisture (2) a method for the production of coatings (especially floor coverings) by applying MCC to a substrate and then hardening it with water, especially atmospheric moisture (3) a covering or coating obtained by this method (4) structures or buildings with such coverings or coatings .
