Abstract
The present invention relates to laminates of a plasticizer-containing plastic, obtained by bonding by means of a moisture-reactive hot-melt adhesive which comprises at least one aldimine and at least one polyurethane polymer which contains isocyanate groups and is solid at room temperature. The bonded assembly is notable for improved adhesive, particularly following heat/moisture storage or alternating storage. Preferred embodiments of such laminates are bonded films or film-laminated supports, the film preferably being a pPVC film.
