The invention relates to compositions which contain at least one
isocyanate-containing polyurethane polymer P, which is produced from at
least one polyisocyanate and at least one polyol, in addition to at least
one aldimine-containing compound of formula (I). The compositions are
stable during storage and harden quickly under the influence of moisture,
are non-porous and do no not separate rich substances. Said compositions,
the hardened compositions, and the resulting separated products are
odour-less. The compositions can be used as an adhesive, sealant or
coating which exhibit good mechanical properties and adhesion.
