    摘要: A pressure-sensitive adhesive comprising organic fillers, obtainable by a process in which a thermal crosslinker is added in the melt to a polyacrylate copolymer (“polyacrylate”) based on acrylic esters and/or methacrylic esters, at least a fraction of which contains primary hydroxyl groups, at least one organic filler has been or is added to the polyacrylate, the polyacrylate provided with the crosslinker and the filler is conveyed to a coating unit, where it is applied to a web-form coat of a further material and, following application, is homogeneously crosslinked, a process as outlined above, and adhesive tapes furnished with the pressure-sensitive adhesive.
