Abstract: A laminate is provided, more particularly an adhesive tape, comprising a) a release liner having at least one carrier layer (CL) and also, applied to this carrier layer (CL), at least one silicone coating (SC) of specific addition-crosslinked or radically crosslinked pressure-sensitive silicone adhesives, and b) at least one further layer (L1), comprising polyacrylate-based adhesives with low tack at room temperature or heat-activable bondable adhesives which have little or no pressure-sensitive adhesion at room temperature. The use of an arrangement as a release liner is also provided, where the arrangement comprises a carrier layer (CL) and also, applied to this carrier layer (CL), a silicone coating (SC) of specific addition-crosslinked or radically crosslinked pressure-sensitive silicone adhesives.
