Abstract:
Multi-layer composite body comprising a flexible auxiliary carrier and a separation layer arranged on at least one side of said flexible auxiliary carrier, said separation layer in flat contact with a functional layer and modifying the complete or locally limited separation of said functional layer, said separation layer comprising a continuous phase and a particle filler substance in a concentration of approximately 0.01 to 50% by weight relative to the separation layer, whereby the surface of the filler substance particles is completely covered by the continuous phase, the continuous phase comprising an interlinked polyorganosiloxane, and the roughness of the separation layer surface facing away from the auxiliary carrier has a roughness depth Rt of approximately 400 to 50000 nm and an average roughness value of approximately 40 to 5000 nm.
