Adhesive tape used for assembling viscoelastic acrylic acid ester hot melt adhesive which is especially three-layer formed and based on heat crosslinking

The invention relates to an adhesive tape used for assembling viscoelastic acrylic acid ester hot melt adhesive which is especially three-layer formed and based on heat crosslinking, concretely, the invention relates to a double-sided pressure-sensitive adhesive tape of the kind which can be used in particular for achieving very durable bonds at high temperatures. These adhesive tapes, especiallyadhesive assembly tapes for the permanent fixing of articles to substrates, are preferably of multilayer construction. The inventive double-sided pressure-sensitive adhesive tapes are characterized in that: the viscoelastic carrier layer is composed of a photoinitiator-free, thermally homogeneously crosslinked acrylate hotmelt. They are further characterized in that these homogeneously thermally crosslinked acrylate hotmelts have crosslinking sites by way of urethane units. This viscoelastic carrier layer is covered on both sides in each case by adhesive layers, preferably pressure-sensitive adhesive layers; and these
