Abstract
An adhesive tape is disclosed that is useful in the manufacture of ceramic articles, and particularly ceramic electronic components such as capacitors. The tape can be used to adhere a green ceramic article to a rigid surface for handling during the manufacturing operation. The adhesive can be deactivated after the green ceramic article has been laminated and diced to release the laminated and diced ceramic articles. The adhesive tape comprises a substrate; a light-reflective metallic layer on the substrate; a first adhesive layer of a heat stable adhesive composition on one surface of the substrate, and a second adhesive layer on the opposite surface of the substrate. The second adhesive layer comprises a heat stable, radiation curable adhesive composition which loses its adhesive characteristics upon exposure to radiation.
