Abstract

Adhesive bonding of eloxated aluminum to plastic, with a product having at least one layer of a latently reactive adhesive film which has a thermoplastic component having a melting point T(melting) where 35° C.≦T(melting)≦90° C. and contains functional groups that can react with isocyanate and an isocyanate-containing component dispersed in particulate form in the thermoplastic and is essentially deactivated in the region of the particle surface, the particles having a start temperature T(start) where 40° C.≦T(start)≦100° C. and where T(start)≦T(melting).
