Abstract: Adhesive tapes comprise a textile carrier and a pressure-sensitive adhesive, applied on at least one side of the carrier, in the form of a thickened dried polymer dispersion, wherein the unthickened dried polymer dispersion comprises: (a) 30.0 to 98.0 wt % of monomeric acrylates; (b) 0 to 50.0 wt % of ethylenically unsaturated comonomers which are not acrylates; (c) 1.0 to 10.0 wt % of tackifier; and (d) 1.0 to 10.0 wt % of kaolin, wherein a rheological additive is added to the polymer dispersion so that the polymer dispersion has a viscosity before drying of 40 to 100 Pa*s at a shear rate of 10/s and a viscosity of 3000 to 8000 Pa*s at a shear rate of 0.01/s.
