  • Publication number: 20080280145
    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.

  • Publication number: 20080251204
    Abstract: The invention relates to relates to moisture-hardened hot melt adhesive which contains at least one polyurethane polymer of formula (I) which comprises aldimine groups and which is solid at room temperature, in addition to at least one polyurethane polymer P which comprises isocyanate groups, if q in formula (I) represents zero, or if X in formula (I) represents N—R8 with R8 as a substituent of formula (III). The compositions are characterised in that contain visibly less isocyanate monomers and are therefor particularly advantageous from a work-hygiene point of view.
