Patent ID: 8178167

Claim:
A moisture-curing composition comprising a) at least one polyurethane polymer P containing isocyanate groups; b) at least one polyaldimine ALD of the formula (I): c) optionally, an oligomeric polyisocyanate OP where: X is an organic radical of a polyamine carrying n NH 2 groups having a molecular weight of not more than 300 g/mol, following removal of all of the NH 2 groups, and the organic radical does not contain any moieties which in the absence of water are reactive with isocyanate groups; n is 2 to 4; R 1 and R 2 are each a monovalent hydrocarbon radical having 1 to 12 C atoms; or R 1 and R 2 collectively are a divalent hydrocarbon radical having 4 to 20 C atoms and are a part of an unsubstituted or substituted carbocyclic ring having 5 to 8 C atoms; R 3 is a hydrogen atom or is an alkyl or arylalkyl group; and R 4 either is a hydrocarbon radical which has 11 to 30 C atoms and optionally contains heteroatoms, or is a radical of the formula (II): where: R 5 alternatively is a linear or branched alkyl radical having 11 to 30 C atoms, optionally with cyclic fractions and optionally with at least one heteroatom, or is a singly or multiply unsaturated, linear or branched hydrocarbon radical having 11 to 30 C atoms, or is an unsubstituted or substituted aromatic or heteroaromatic 5- or 6-membered ring; and where: the fraction of the polyaldimine ALD of the formula (I) is in an amount of at least 22% by weight, based on the sum of the constituents of the composition that contain isocyanate groups.
