摘要： The present disclosure relates to an aqueous dispersion containing at least one semicrystalline polyurethane-polyurea polymer and at least one surface-deactivated polyisocyanate. The melting temperature of the semicrystalline polyurethane-polyurea polymer is at least 55° C. The disclosure also relates to a process for preparing the aqueous dispersion, the use of the aqueous dispersion for producing coated substrates or adhesive films, flat or three-dimensional substrates coated with the aqueous dispersion, a substrate coated with at least one semicrystalline polyurethane-polyurea polymer and at least one surface-deactivated polyisocyanate, an adhesive film including at least one semicrystalline polyurethane-polyurea polymer and at least one surface-deactivated polyisocyanate, and a dried adhesive film obtained from such an aqueous dispersion.
