Abstract
The invention primarily concerns a pressure-sensitive adhesive tape, the adhesive layer of which is filled with glass microbubbles and has a dark appearance by virtue of the microbubbles having a thin-film coating having an average thickness from 0.05 to 30 nm. A preferred thin-film coating is silver which can be applied by sputtering or by vapor deposition, preferably to an average thickness of between 1 and 10 nm.
