    Abstract: The invention relates to a double-sided adhesive tape, comprising a carrier layer and two exterior pressure-sensitive adhesive compound layers, wherein at least one of the pressure-sensitive adhesive compounds is the crosslinking product composed of a polymer compound which comprises at least the following components: A) a polymer component (component A) comprising 88 to 100 wt % of one or more polyacrylates (component A1) composed of at least: a) 1 to 15 wt %, relative to component A1, of one or more monomers having at least one ethylenically unsaturated bond, each being selected such that the glass transition temperatures TG of the corresponding homopolymers composed of the respective monomers are at least 0° C. (monomers a), wherein at least some of the monomers (a) still comprise at least one carboxylic acid (monomers a1), b) 85 to 99 wt %, relative to component A1, of one or more monomers from the group of acrylic acid esters and methacrylic acid esters, each being selected such that the glass transition temperatures TG of the corresponding homopolymers composed of the respective monomers are not higher than −30° C. (monomers b), B) at least one covalently cross-linking bifunctional or polyfunctional crosslinking agent (component B), wherein components A and B in total amount to at least 95 wt % of the polymer compound, and wherein the at least one crosslinking agent is added in a quantity such that the quantity ratio V=nZ/nP of the substance quantity nZ of the crosslinking-active centers of the crosslinking agent to the theoretical substance quantity nP of the macromolecule of polymer component A1 has a value between 0.15 and 0.60, wherein the substance quantity nZ of the crosslinking-active centers of the crosslinking agent is obtained from the mass mV of the crosslinking agent, multiplied by the number f of crosslinking-active centers per crosslinking agent molecule, divided by the molecular weight Mv of the crosslinking agent, that is, nZ=f·mV/MV, and the theoretical substance quantity nP of the macromolecule of polymer component A1 is obtained from the mass mP of the polymer component in the pressure-sensitive adhesive compound, divided by the average molecular weight Mn,P of said component, that is nP=mP/Mn,P.

    Abstract: The invention relates to pressure-sensitive adhesive tapes for flying splice of flat web materials, having at least one splittable carrier and two layers of adhesive, at least one of the adhesives being a silicone PSA, more particularly an electron-beam-crosslinked silicone PSA, and also to a method of producing them. The silicone PSA advantageously has at least one polydiorganosiloxane having the structure —Si(R2)—O—[Si(R2)—O]n—Si(R2)—, where the 2n+4 substituents R independently of one another are monovalent hydrocarbon radicals and n is an integer, and also at least one resin (“MQ resin”) constructed from (R2)3SiO1/2— units (“M units”) and SiO4/2 units (“Q units”), the substituents R2 of the M units being independently of one another alkyl groups, alkenyl groups, alkylsilyl groups, hydroxyl groups or hydrogen.
