Abstract
A composition having at least one polyisocyanate and/or at least one isocyanate-group-containing polyurethane polymer and at least one latent hardener having aldimino group(s) of formula (I)—as an elastic adhesive, sealant or coating, which is applied on at least one plasticiser migration sensitive substrate and/or is provided with at least one covering layer and a composite obtained therefrom. The method is characterized in that porous material or stress-crackforming plastics can be used without restriction as substrates and very different materials can be used without restriction as covering layers, without the occurrence of damage associated with plasticiser migration from the composition, such as bleeding, discoloring, spotting, softening, swelling or detachment.
