摘要: 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.

摘要: The invention concerns glass microbubbles having an inorganic thin-film coating not exceeding about 10 nm in thickness, especially a coating of a metal, a metalloid, or an alloy thereof. When dispersed throughout a matrix such as a polymer, the coated glass microbubbles can afford surprisingly good hiding power while also imparting esthetically pleasing colors to otherwise transparent articles.

摘要: A marker for use in magnetic-type electronic article surveillance systems, comprising a substrate on which are deposited a plurality of high permeability, low coercive force magnetic thin-films, each being separated from an adjacent magnetic thin-film by a non-magnetic thin-film. Each of the magnetic films have substantially the same permeability and coercive force, and the non-magnetic films are of a thickness to allow magnetostatic coupling while inhibiting exchange coupling. Accordingly, all of the magnetic thin-films reverse as a single entity and produce a sharp, readily distinguishable response.
