Abstract: Pressure-sensitive adhesives based on acrylonitrile-butadiene rubbers having good shock-resistance combined with easy removability of the adhesives from the substrate shall be provided. This is solved by a pressure-sensitive adhesive which comprises at least one acrylonitrile-butadiene rubber; and at least one tackifier resin, and is characterized in that the acrylonitrile content of the acrylonitrile rubber is less than 30 wt %; the pressure-sensitive adhesive comprises at least one rosin resin as tackifier resin; and the entirety of all tackifier resins has an acid number of 6-150. The pressure-sensitive adhesive can be used for bonding parts in mobile electronic devices.
