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—R8with R8as 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.
