Process for producing adhesive tapes in which adhesive tapes coated on one side with an adhesive composition are subjected to radiation crosslinking, the irradiation of the adhesive tape taking place through the backing material of the adhesive tape onto the adhesive composition in such a way that the backing material and that side of the adhesive composition facing the backing material receive a dose of from 30 to 200 kGy, in particular 100 kGy, and the acceleration voltage during the irradiation being chosen such that the dose on the open side of the adhesive composition has fallen from 0 to 60 kGy, in particular from 10 to 20 kGy.

An air-permeable filter material for use on doors, door frames, windows or window frames and a method of using the filter material to protect against the ingress of pollen and dirt particles in the environment. The filter material may be composed of fabric or film or a combination of film and fabric, the material having perforations of a diameter of 2-250 .mu.m, and a fixing material for applying the filter material.
