Abstract:
1. A laminate comprising a) at least one substrate S1; b) at least one hot-melt adhesive K comprising c) at least one substrate S2, the substrate S1 and/or the substrate S2 being a plasticizer-containing plastic, the substrate S1 and/or the substrate S2 having been pretreated, where appropriate, with a primer, and the substrate S1 being joined to the substrate S2 via the hot-melt adhesive K, wherein the hot-melt adhesive K reduces a gradual loss of adhesion between the adhesive and the substrate that is the plasticizer-containing plastic as compared to a same hot melt adhesive that does not contain the at least one aldimine A, wherein the polyurethane polymer P is prepared from at least one polyisocyanate and a mixture of at least one amorphous polyester diol with at least one polyester diol that is liquid at room temperature.
