    摘要: Process for producing a flexible, planar carrier coated with a porous adhesive layer, characterized in thata) a flowable adhesive composition is applied to an intermediate carrier having the following properties:it has a microscopically undulating, pleated, fissured or furrowed surfacethe adhesive composition can be easily detached from the surface thereofit is essentially air-impermeable,b) the microscopic air or solvent inclusions resulting, after coating the intermediate carrier, between the adhesive composition and the intermediate carrier are expanded by increasing the temperature until the surface of the adhesive composition bursts, andc) the adhesive composition is subsequently transferred from the intermediate carrier onto the final carrier.
